You obviously broke the rules and now you have to deal with the consequences, chances are very slim that you will receive money back but by all means try your hardest.

Try finding Xbox supports number. I've had to deal with them before. Prepare to deal with the most incompetent people you will ever speak with..

ok ill try my hardest

Look at your e-mail and see what "you did wrong". And if that is not true, contact microsoft.

I had a xbox live account that got suspended, and i was claimed to be a gamescore hacker, or something like that. So for me there were no chance of getting it back.

But if you havn't been doing gamescore hack or anything like that, i don't think it will be that hard to get it back.

Nothing you can do, sorry
Just make another account or Phone Microsoft up and try to get your XBL back
