Refund credit card payment renewal; replace it with product key

Contact Microsoft Billing Support promptly and ask them to refund only yesterday’s recurring credit-card charge while preserving the year added by the redeemed product key.

The standard self-service refund process cancels the subscription, but Microsoft’s documentation does not guarantee that cancellation will preserve separately stacked prepaid time. A closely matched case—an unintended card renewal followed by redemption of a 12-month code—recommends having Support adjust the billing rather than risking cancellation of the combined subscription period.^1^

Request the billing adjustment

1. Before making changes, open Microsoft account → Services & subscriptions and record:
   • The displayed Microsoft 365 Personal expiration date.
   • The recurring credit-card transaction and date.
   • The product-key redemption receipt or confirmation.
2. Open Contact Microsoft Support, sign in with the Microsoft account that owns the subscription, enter the billing issue, select Get Help, and then select Contact Support.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
3. State the request precisely:

   Please refund only the Microsoft 365 Personal recurring billing charge from yesterday. A prepaid Microsoft 365 Personal key was subsequently redeemed on the same subscription. Please preserve the prepaid year and adjust the expiration date by removing only the card-funded renewal period.

4. Ask the agent to confirm the resulting expiration date before approving any cancellation or adjustment.

Microsoft treats redeemed keys as additional subscription time: multiple keys stack time on the existing subscription, up to a maximum subscription duration of five years.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "How to renew your Microsoft 365 subscription | Microsoft Support")

Refund eligibility

Microsoft’s policy states that the most recent recurring billing charge is refundable when cancellation occurs within 30 days after payment, limited to one time per Microsoft account per subscription product.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support") Since the charge occurred yesterday, make the request immediately.

If Support directs you to self-service cancellation, first ask them to confirm in writing that the redeemed prepaid year will remain. Ordinarily, the path is:

Services & subscriptions → Microsoft 365 Personal → Manage → Cancel

Eligibility is determined automatically during that process, and not every cancellation produces a refund.[^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365")

After the adjustment, check Services & subscriptions again and verify:

• The card renewal was refunded.
• The expiration date still includes the prepaid year.
• Recurring billing is off if no further automatic renewal is wanted.

The prepaid code itself is not covered by Microsoft’s subscription refund policy; prepaid retail codes follow the retailer’s return policy. That should not matter here because the requested refund concerns the separate recurring card charge.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
