I just ran to the store and when I returned, I was signed out of XBox Live. I tried to sign back in, and was told my information was incorrect, so I went through the process to change my password. When I logged in, I saw I had 8400 extra Microsoft Points that I did not purchase. My email inbox also had 3 confirmation of purchase emails in it. If someone did use my account to buy Microsoft points, it won't reflect in my bank statement until later so I can't check there and Customer Support line was of no help. What do I do? How do I check what method was used to buy the points?
