Purchases made by mistake

If those purchases were not intended, first verify whether they appear in Microsoft order history and whether they came from the same account.

1. Sign in to the Microsoft order history page and look for both $99.99 purchases.
2. Check whether there are two separate purchases for the same item and amount close together.
3. If the charges appear on the bank statement but not as duplicate purchases in order history, check whether another Microsoft account may be using the same card. In Payment options, select Investigate.
4. If the purchases are confirmed and were made by mistake, contact Microsoft Support through Contact Microsoft Support, enter the problem, select Get Help, and then Contact Support for the best support option.
5. If the charges are unauthorized, contacting the card provider to dispute the transactions is also supported in the provided guidance.

The context does not provide a direct self-service way to remove those purchases immediately. The supported path is to review order history, investigate whether another account used the card, and then contact support for account-specific billing help.
