First off- wrong section this needs to go in the unban section.
Second- You've been banned a week or more and your just now saying something about it?
Something seems odd about this. We need more info about the situation.
Where you banned and then bought admin? In that case I think the ban would stay until you've served your time.
If you bought admin after a perma ban thanks for the money but your not getting unbanned.
If you got banned on accident than sorry and welcome to the wonderful wold of IBIS admins. Zero will need your steam id to unban.
