Last night, before I went to bed, I noticed I had ~1500 MS points. When I woke up this morning, I had 10. Upon looking at my download history, I found two items purchased today.
SILVER PLAYERS PREMIUM and PREMIUM GOLD JUMBO are, from what I can gather, something for sports games.
When I checked my e-mail, I had a message that said my credit card declined for the purchase of 6000 MS points. I didn't see any charges in my online statement, but it usually takes a few days for things to show up there anyway. I know I bought two 1600 MS points packages in the past few months, but nothing but that.
Is there anything I can do to get my points back?
