Banned for earning credits on halo reach

Ok I’ve received a credit ban on halo reach and I haven’t done anything wrong. First it was my profile is banned from earning credits, now it’s my console and profile. There is no banned for a week or anything. I’ve contacted Microsoft support. They checked my profile and account and there is no ban on it. I can’t play my account, as I don’t gain any credits.
I don’t know what to do. I need help, dam Xbox live.

This topic is better suited for the Halo: Reach Forum.
