Best advice is come back every 2 weeks or so and bump thread, and send a nice email reminding them you are waiting.  This is a slow process as you will find out posting every few day's will not help. 

But give it some time and see what happens.  There is no guarantee you will be unbanned if you want honest truth.  So if they do it they are being very nice.  So best advice make sure during this time not to ban evade with another account, and wait with bumps every two weeks or so.
