Over the weekend, my credit card was charged for microsoft points, a purchase I did not make, and probably will never make. That leads me to think that someone got into this account. So right now, somebody knows my account name, password, address, and etc. I've changed my password when I found out. I do not know how that person got into this account, but I am lucky enough that I haven't had my account stolen. Does anybody know what I should do for this account?
