Fraudulant buy with my card

You can check the previous purchases made on your Mircosoft account at https://account.microsoft.com/billing/orders?fref=home.card.payment-and-billing along with
an approximate location of where the purchase was made. If you find a corresponding transaction there, this means the purchase was made through your own Microsoft account. You can contact Microsoft Support at support.microsoft.com/contactus To avoid further
fraud, I would highly recommend you change your password and check out additionnal security options at https://account.microsoft.com/security?fref=home.card.security

If the purchase was not made on your account, the issue must be resolved with the provider of the payment method used.

For billing issues contact xbox support: (800) 469-9269 if you're in the US/Canada or

I agree. That was my issue --- fraudulent charges on the credit card. I contacted the credit card company, and they addressed the problem. Unauthorized charges and a compromised card number may be what happened in your situation, too.

I would like to add that these charges are unlikely being made by Microsoft.

Rather someone has probably stolen your credit card information and is using it to buy content fraudulently. If that is the case, only your bank can deal with these transactions.
