banned from earning points???

Ok so I turned on my 360 and loaded halo anniversary multi-player and a message popped up saying that my xbox has been temporarily banned from earning points. Then I got another message saying my account cannot earn points either. What do I do???

You have been credit banned, theres nothing you can do.

343 ban both the account and console so that offenders cannot just rank up another account. You can still play but cannot rank up until the ban expires.

Did something wrong obviously.
