How do I get unblocked from earning credit?

In the last couple days signed up to xbox live, way better than playing firefight etc, but now for some reason I’ve been blocked from receiving credits for games (I need credits as all my points are in my offline profile).

I have no idea how to have this resolved, I haven’t done anything that I’m aware of could have me blocked.
All I’ve done is play, no chat or anything.
If anyone can help me out on how to get this sorted that would be awesome, cheers :slight_smile:

Are you simply not receiving any XP from playing or are you seeing a message telling you that you have been banned from earning XP?

I’m receiving the message saying I’m banned.
