Is there a method to unban

I got ban for beating a group of 2 with 4 people in a group. And we did not used in hacks. To smack this cheating group. But I got ban and the 2 other people we was with

write to support and ask why did you got banned

Pretty sure this won't help him get unbanned.
If you log on using various IP's through out the week, maybe you can say you got hacked, but probably unlikely, because they might check your mac address
