I just purchased a new Slim Xbox 360 and when I went to download some old DLC I realized that a lot of my Microsoft Points were missing (I just activated a 4,000-point card last month). I logged onto both xbox.com and billing.microsoft.com and they both show several downloads that I never purchased.
10/13/11 - Battlefield: Bad Company 2 (-1,600)
I now realize I was missing 1,600, just never noticed because of the extra 4,000 I had added. I have no need to own this game, I played it enough when I owned the disc.
11/1/11 - Shotguns Launch Collection Weapon Skin - Gears of War 3 (-1,200)
11/1/11 - Cerberus Network - Mass Effect 2 (-1,200)
11/1/11 - Horde Command Pack - Gears of War 3 (-800)
11/1/11 - Mark of the Assassin - Dragon Age II (-800)
I have never played Gears of War 3 or Dragon Age II (my Recent Games will show that) and I know 100% that I never downloaded the Cerberus Network for Mass Effect 2.
Thinking about it now, recently (probably around 11/1) I was forced to change passwords when trying to access one of Microsoft's sites. Does this mean I was hacked? Or was there a glitch with the system? I haven't noticed anything else wrong with my account so far.
Not really sure where to go from here, any help would be much appreciated.
