The only thing I have found is create a new account and buy the game again....Make sure you save your sign on setting form the previous account if you have more games on it other than the one game you were banned on. Sorry...This is what happened to me in advanced warfare under steam. I don't know Repz..
Don't forget to go to properties in your banned account and delete local content before you install the new game in the other account if you are on the same I.P. There are a lot more people here that know a lot more than I do maybe they can give you better info...Merry Christmas and Happy New Year.
