How to cancel your Ahm OSHC policy and protect your student health cover in singapore
Understanding Ahm and what you are really cancelling
Ahm is a mobile application published by Medibank that manages Overseas Student Health Cover (OSHC) for international students. If you are accessing Ahm from Singapore, you are likely managing health coverage tied to study or work arrangements outside Singapore. Your first step is to confirm what you are actually cancelling: the app itself, your active OSHC policy, or both. These are separate actions with different legal consequences, and getting this distinction right protects you from unexpected charges.
What Ahm is and what it is not
The Ahm app is a free utility available on the Singapore App Store. It lets you manage your OSHC policy, submit claims, view coverage details, and communicate with Medibank. It is not a paid subscription service sold in Singapore. Instead, it is a companion tool for an existing OSHC insurance policy you hold as an overseas student or temporary resident. Removing the app does not cancel your underlying policy; cancelling your policy will automatically remove your app access. At Yafee, we emphasise this distinction because many consumers uninstall the app thinking they have cancelled their policy, only to discover months later that they are still being charged.
Why you might choose to cancel
You may decide to cancel your Ahm account or OSHC policy if you are returning to Singapore permanently, switching to a different health provider, completing your studies, or changing employment status. Each reason carries different refund implications under Singapore consumer law. Your cancellation right depends on whether you are within a cooling-off period, whether you have material grounds to dispute the policy, or whether you simply wish to exit an active contract. Yafee has helped thousands of consumers understand exactly what they are cancelling before they take action, so you avoid costly mistakes and preserve your legal entitlements.
Your consumer rights under singapore law
Your rights as a consumer in Singapore are protected by the Consumer Protection (Fair Trading) Act (Cap. 52A), even when you are managing health coverage tied to overseas arrangements.
What the consumer protection act guarantees you
The Consumer Protection (Fair Trading) Act protects you against unfair contract terms, misleading statements about coverage, and unreasonable cancellation barriers. If Medibank or your OSHC provider has misrepresented the terms of your policy, you have grounds to dispute charges or demand a refund. You are also entitled to clear, written confirmation of any cancellation you request. Keep all communications in writing: emails, payment receipts, policy documents, confirmation numbers, and screenshots of the app. These form your evidence trail if you need to escalate a dispute to the Consumers Association of Singapore (CASE).
Cooling-off periods and your protection
Many insurance policies in Singapore, including OSHC arrangements, offer a cooling-off period (typically 14 to 30 days) during which you can cancel without penalty or receive a pro-rata refund. Your OSHC policy document will specify this window. Check your policy documents immediately to see whether you fall within it. If you do, write to Medibank or your OSHC provider within the specified timeframe to preserve your right to a refund. Do not delay: this period is absolute, and missing it may forfeit your refund entitlement.
Your legal position: what you can demand
You have the right to cancel your OSHC policy at any time by providing written notice. You are entitled to receive a clear, dated confirmation of your cancellation request. If you are within a cooling-off period, you can demand a full refund. If you are outside a cooling-off period but have grounds to dispute the policy (misrepresentation, breach of contract, unfair terms), you can escalate to CASE. Medibank must not impose unreasonable cancellation fees or require cancellation only via phone. If they do, this violates consumer law.
Step-by-step cancellation methods
Cancelling your Ahm OSHC requires a direct approach: written communication is your strongest tool because it creates a paper trail and meets statutory requirements.
Prepare your cancellation request
Before you contact Medibank or your OSHC provider, gather these essentials:
- Your full name and date of birth
- Your policy number or account number (visible in the Ahm app under Account or Policy Settings)
- The email address and phone number registered to your policy
- Your intended cancellation date
- Your reason for cancellation (optional but helpful for refund assessments)
- Proof of payment (credit card statement, policy invoice, or app transaction history)
- Any communication from Medibank relating to your policy
Critical step: Screenshot or download your policy details, coverage summary, and payment history from the Ahm app before you submit your cancellation request. You will lose app access immediately after cancellation is processed, and you may need these documents for refund disputes or tax purposes.
Cancellation via written request (recommended method)
Writing to Medibank or your OSHC provider creates a documented cancellation record and gives you statutory proof. Follow these steps:
- Compose a formal cancellation letter or email containing:
- Your full name, date of birth, and policy number
- A clear statement: "I request cancellation of my OSHC policy effective [date]"
- Your reason for cancellation
- The address or email to which you want confirmation sent
- Your signature (if posting)
- Send your request via registered mail, email with read receipt, or through the Ahm app's secure messaging feature (if available). Do not use standard mail without tracking.
- Note the date and time you sent the request. Keep a copy of the letter and the proof of sending (delivery confirmation, email receipt, or app timestamp).
- Wait for Medibank's written confirmation. They must acknowledge your request within 5 working days and confirm the cancellation date and any refund due within 14 days.
- If you do not receive confirmation within 14 days, send a follow-up request with your original request attached.
Cancellation via phone (if written is not available)
If Medibank requires you to cancel by phone, you can call the Ahm support line. However, this method is weaker because you will not have a written record. Follow these steps:
- Call the Ahm customer service number (typically +61 2 8003 8200 for Australian customers; verify the correct number for Singapore-based calls via the Ahm app).
- Have your policy number and personal details ready before you call.
- Request the name and employee ID of the person handling your cancellation.
- Say clearly: "I want to cancel my OSHC policy effective [date]. Please confirm this in writing within 5 working days."
- Ask them to send you a cancellation confirmation email immediately after the call.
- If they refuse, say: "I am requesting cancellation in writing by email instead" and switch to the written method above.
Cancellation through the Ahm app (if available)
Some versions of the Ahm app offer an in-app cancellation option. If you see a "Cancel Policy" button in the app's Account or Settings menu:
- Tap the option and select your cancellation reason.
- Review the cancellation summary and confirm your intended cancellation date.
- Submit the request and note the confirmation number shown on screen.
- Take a screenshot of the confirmation page immediately.
- Wait for a confirmation email from Medibank within 5 working days and verify the cancellation date matches what you requested.
Understanding refunds and timelines
Your refund entitlement depends on when you cancel and your reason for cancellation.

Claiming your refund
Medibank will process your refund to the original payment method (credit card, bank account, or other payment source). You do not need to request this separately if you have cancelled in writing; it is automatic. If you do not see the refund after 28 days, contact Medibank in writing with your cancellation confirmation number and request a refund status update. At Yafee, we advise keeping your bank statements for at least 60 days after cancellation to verify the refund has been received.
What happens after your cancellation is processed
Cancellation is not instant, and you need to know what to expect during the transition period.
Your coverage during the cancellation process
Your OSHC policy remains active until the cancellation effective date you specified. If you specified immediate cancellation (today's date), coverage ends at the end of that day. You remain entitled to claim for any covered services received before the effective date, provided you submit claims within your policy's claims deadline (usually 90 days). Do not assume your coverage has ended until you receive written confirmation from Medibank.
App access and your records
The Ahm app will become inaccessible once your cancellation is processed. Download or screenshot your complete coverage history, claim records, and policy documents before the effective date. You may need these for tax purposes, visa applications, or future insurance underwriting. Medibank will retain your records and can provide copies on request, but accessing them via the app becomes impossible after cancellation.
Switching to alternative health coverage
If you are remaining outside Singapore and need continuous health coverage, organise your replacement policy before your Ahm cancellation effective date. A gap in coverage may create visa or work permit complications depending on your country of residence and visa conditions. Do not cancel Ahm until your new policy is confirmed and in effect.
Common cancellation mistakes and how to avoid them
Most cancellation problems stem from simple procedural oversights, and they are entirely avoidable if you follow this guide.
Mistake 1: confusing app deletion with policy cancellation
Uninstalling the Ahm app from your phone does not cancel your OSHC policy. Medibank will continue to charge you until you formally cancel the policy in writing. Check your bank statements monthly to confirm you are not being charged after you intended to cancel. If you find charges after the intended effective date, you have grounds to dispute them and demand a refund plus compensation for unauthorised charges.
Mistake 2: cancelling by phone without written follow-up
Phone cancellations leave no paper trail. If Medibank later claims they never received your cancellation request, you have no proof. Always insist on written confirmation via email or certified mail. If they refuse, submit your cancellation request in writing instead and keep proof of sending.
Mistake 3: missing the cooling-off period deadline
Your cooling-off period is absolute and non-negotiable. If your policy document states 30 days and you submit your cancellation on day 31, you forfeit your right to a full refund. Check your policy document immediately and mark the cooling-off deadline in your calendar. If you are close to the deadline, cancel in writing today rather than delay.
Mistake 4: failing to document your cancellation request
Keep every communication: emails, screenshots, letters, confirmation numbers, delivery receipts, and bank statements. If a dispute arises, Medibank's system may have errors or claims your request was never received. Your documented evidence is your only protection. Yafee recommends maintaining a folder (physical or digital) with all OSHC-related communications for at least 2 years after cancellation.
Mistake 5: cancelling before confirming your replacement coverage
If you need continuous health coverage outside Singapore, do not cancel Ahm until your new policy is active. A gap in coverage can affect visa status, create barriers to future claims, or leave you uninsured in a medical emergency. Coordinate your cancellation effective date with your new provider's start date.
What to do if medibank refuses to cancel
If Medibank does not respond to your cancellation request or claims they cannot cancel, you have clear remedies under Singapore law.
Step 1: escalate in writing
Send Medibank a formal letter (not email, unless they have confirmed they accept email for cancellations) stating: "I am formally requesting cancellation of my OSHC policy effective [date]. You have 7 days to confirm this cancellation in writing. Failure to do so may constitute a breach of contract and consumer law." Keep proof of sending (registered mail receipt or email read receipt).
Step 2: contact CASE (Consumers association of singapore)
If Medibank does not respond or refuses your cancellation request without legal grounds, lodge a complaint with CASE. CASE is Singapore's official consumer dispute resolution body and can mediate on your behalf. You can file a complaint online at www.case.org.sg. Provide CASE with all your communications, policy documents, and evidence of your cancellation request. Yafee notes that CASE mediation is free and often resolves disputes within 4-6 weeks.
Step 3: demand a refund in writing
If you are within a cooling-off period, demand a full refund. If you are outside a cooling-off period but have grounds to dispute the policy (misrepresentation, unfair terms, breach of contract), demand a refund and compensation for losses. Send this demand via registered mail to Medibank's registered office address and keep proof of sending.

Sending your cancellation request to medibank
Once you have prepared your request and gathered your documents, send your cancellation letter to the correct address or email depending on your policy type.
Mailing address for standard health cover cancellations
Send your cancellation request via registered mail to:
Medibank Limited
Customer Service Team
GPO Box 9803
Sydney NSW 2001
Australia
Include a note at the top of your letter: "Re: OSHC Policy Cancellation Request - Policy Number [Your Number]". Allow 2-3 weeks for mail transit time and 5 working days for Medibank's response.
Email method for faster cancellation
If Medibank has provided an email address for cancellation requests (check your policy document or the Ahm app's Contact section), send your cancellation letter as an email attachment with the subject line: "OSHC Policy Cancellation Request - Policy Number [Your Number]". Request a read receipt and ask Medibank to confirm your cancellation within 5 working days. Keep the email in your inbox as proof of sending.
In-app cancellation portal (if available)
If the Ahm app has a secure messaging or support portal, you can submit your cancellation through it. This creates a timestamped record within Medibank's system. Screenshot the confirmation message immediately after sending.
Summary and next steps
Cancelling your Ahm OSHC policy is straightforward if you follow a structured approach: gather your documents, understand your refund entitlement, and submit your cancellation request in writing.
