I was billed twice for my subscription

To request a refund for a double charge on a Microsoft subscription:

1. First investigate the extra charge on the Manage your payments page and select Investigate if the charge is not recognized.
2. If the extra charge is tied to a subscription purchased directly from Microsoft, sign in to Services & subscriptions at Sign in.
3. Find the subscription and select Manage.
4. Select Cancel or Upgrade or Cancel.
5. During cancellation, Microsoft automatically determines whether the subscription qualifies for a refund and shows the next steps.

Important details:

• Not all cancellations result in a refund.
• In most cases, a refund may be available within 30 days of the initial purchase or before the first recurring billing date, whichever is sooner.
• A refund of the most recent recurring billing charge may also be available if cancellation happens within 30 days after payment. This right is limited to one time per Microsoft account, per subscription product.
• If no refund is issued, access to Microsoft 365 typically continues until the end of the current billing period.
• If the subscription was purchased through Google Play or the Apple App Store, the refund must be requested from their support, not Microsoft.
• If Turn on recurring billing appears instead of Manage, the subscription is already set to expire and no further cancellation action is needed.

If the charge still cannot be identified, use the billing troubleshooter from Microsoft support.
