Hi I've recently redeemed a 1600 ms point card and it was redeemed successfully and points were indeed added to my account. I went to the game marketplace with my 1620 ms points (I had 20 points in my account when I redeemed my card) and tried to purchase Splinter Cell: Chaos Theory for 1200 ms points. The window to confirm the transaction appeared and I confirmed. Then a message say that Xbox Live was currently unavailable and the game didn't download. Despite this all xbox live options were available and I could chat and play with my friends. I went to my account settings and looked at my MS balance and it said information not available. So I turned off my console and waited. When I turned on my console and checked my MS balance it said I had 420 points left. So I checked my purchase history and Splinter Cell was not there. Then I went to the game to see if it had the option to re-download it. Instead of having a check mark to say that I purchased it it had the cost to buy still their. So I selected the buy option and then the confirmation window came up saying that it would cost 1200 points. I rechecked my balance and I had 420 points. Xbox Live STOLE my money. Until this issue is addressed and fixed I can assure that Microsoft won't see another penny from me.
