Is it acceptable for Microsoft to steal subscription time?

Request a transaction-level review from Microsoft 365 account support, asking them to verify the redeemed key’s SKU, the option recorded during redemption, and the conversion rate applied before deciding whether three months should be restored.

Microsoft documents that when a Personal key is redeemed against an active Family subscription, the customer should be offered a choice: retain Family and receive prorated time, or switch to Personal. Retaining Family can add less than a year because Family costs more.^1^

The same page gives a 9-month Family/12-month Personal example, but that example concerns a free offer supplied with a computer. It does not establish that exactly nine months was correct for your Amazon UK retail key. Current switching guidance uses percentage-based conversion and says the recorded choice determines whether the plan switches or the time is prorated.^2^

Submit a focused support request

Since your previous attempt has not resolved it:

1. Open Microsoft’s Contact us page and sign in using the exact Microsoft account on which the key was redeemed.^3^
2. Select Microsoft 365 and then the subscription/account-billing option offered.
3. Choose live chat or another agent-assisted option if displayed. Availability depends on the account, region, and issue.
4. Use wording such as:

   Please review the redemption transaction for my Microsoft 365 Personal retail key. The redemption page identified Personal benefits, but the completed transaction retained Microsoft 365 Family and credited nine months. Please confirm the key SKU, the plan-selection value recorded during redemption, the pre-redemption expiration date, and the conversion rate applicable on the redemption date. If Personal was selected or the wrong conversion was applied, please correct the subscription term.

5. Ask for a case/reference number and retain the chat transcript.

Include:

• Amazon invoice showing Microsoft 365 Personal and purchase date.
• Photograph or screenshot of the product packaging/listing, with the key itself obscured.
• Current subscription name and expiration date.
• Previous Family expiration date, if available.
• Screenshot showing “Microsoft 365 Personal Benefits.”
• Any redemption confirmation email.
• Date and approximate time of redemption.
• Previous support case numbers.

Do not post the 25-character key publicly.

Check who manages the subscription

At the Microsoft account Subscriptions page, select Manage for Microsoft 365.^2^

• If Microsoft management options are available, continue with Microsoft support because it can inspect the account redemption.
• If the page identifies Amazon as the subscription manager, billing, cancellation, or refund action may need to be handled by Amazon. Microsoft support should still be asked to identify what SKU its redemption system received and how it was applied.

When to pursue Amazon

Contact Amazon only if Microsoft determines that:

• the supplied key was not actually a Personal key;
• it was invalid, blocked, or incorrectly described; or
• its supplied terms differed from the listing.

Microsoft’s guidance says a nonworking or improperly supplied retail key should be taken back to the seller for refund or replacement.^4^

A three-month restoration is not guaranteed: the decisive question is whether you selected switch to Personal, whether the system instead recorded retain Family, and which conversion terms applied to that retail key in February 2026.
