Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,
If you have been charged twice for the same subscription, the refund will be automatically initiated within a few days.

Make sure the second charge for the same subscription isn't from another Microsoft account or a family member's account. If the charge is from a different Microsoft account, visit the Services & Subscriptions page to cancel the subscription. After cancellation, you'll receive a confirmation email, and the refund will be automatically issued within 3-5 business days.
