Why am I banned for no reason?

Well, it’s simple, I was banned from halo reach as far as credits are concerned, with the message “This xbox 36 console is excluded from earning credits temporarily” and the same with the account, the reason? Well, that is the problem, there is no apparent reason, maybe play a lot is a reason, reach the limit of daily credit maybe, but not so, neither is a reason, I do not understand, I play infection, invasion and in part Anniversary firefight, after playing that, clearly to complete a challenge, specifically the one to play 150 waves, I’ve been doing it all day, I can not say that I earn many credits, I took like 1000 every 15 minutes that lasted that, when alone I was missing 20 rounds, I took a break and went for food, what’s up? That when I return I’m banned, right? I hope I knew it, this is very unfair and I really hope they could raise that ban, not to mention that just yesterday they took away the other ban that they had put me for the same reason, just to play Griffball for a while, so you can not, it’s very frustrating.
