For queries about matchmaking bans you should use the pinned thread at the top of this forum for further help.
If your console has indeed been banned however, buying another copy of the game would not work. You would need to purchase a new console and very likely start a new Xbox Live account. If it is just you account that has been banned then you would need to use a different account to play online.
