Falsely banned for misconduct?..

i highly doubt it was for no reason. and if it was, you have no reason to complain. when you signed up you agreed that you never have done, nor will you ever, own the account. it is 100% nexons, and they can do anything to it they like. ban it, delete the characters, rename characters, make you a gm, whatever, you just don't have a leg to stand on, and logging a ticket probably wont help.
