Someone made four separate Microsoft XBOX purchases on the same day (12-19-23) all in the amount of $52.42 using my checking account information. I had a Windows 365 account that I was paying monthly on that was using my checking account as a source of payment. Wasn't sure if someone hacked my windows account and stole the checking information or what. So I had the Microsoft 365 account cancelled last night and the payment information removed. How do I trace those charges back to see what they were for? The person w/Microsoft support that helped me to get the Microsoft 365 account closed said that I would have to get with XBOX support to determine that.
