Support??? What support...lol
I see people mod everyday, and I report them ( not saying you did ) and nothing ever gets done about it.
Since Ghost came out XBox Live stopped monitoring BO2 like they use to, and people know it so they start using their mods and cheats, and get away with it. And Activision never monitored anything like they should have.
And if you do get banned good luck getting a reason why... they have your money, they could care less.
