I found I lost 1200 microsoft points today. After checked the download history, I found that I purchased blackops new map pack. I don't even own the game!! Then I realized my friend seated on one of my controller and turned the xbox on yesterday. Because blackops map pack is the first tag come out after xbox is on, I guess what happened was my friend seated on the controller and A button was clicked 3 or 4 times. Then Bang! I lost $15 bucks.
I don't want my money back, but I really want let you guys realize it's a bad design. People may turn on their xbox without turn on TV mistakenly, and after mistakenly press buttons their may purchase items they don't need.
