According to the records, your account has been banned since November, 2013, for illegally hacking the game and posting illegally modified cars on the Auction House. I believe, if you originally read the ban message, you may have noted something about being banned for 20 years. That is permanent.
However, neither bans nor the enforcement of the Xbox Live Code of Conduct by Turn 10 are discussed on these forums. You may send an email to the developers at firstname.lastname@example.org.
