Hello,
If you have been charged twice for the same subscription, the refund will be automatically initiated within a few days.
Before proceeding, ensure 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.
