I remember some months (maybe a year+) ago I had 2,000+ MS points on my Xbox Live account. I log on just recently (after not playing for a while) and my balance is sitting at 0. Curious, I checked out my MS account transaction page and it says all of my points (2,160) EXPIRED some months ago. How is this even possible?! I PAYED FOR THOSE POINTS! This must be some kind of mistake!
