If it states suspended, it is not perm. However, at least you have gotten a response. I first joined Nexon in 2008---I have 3 tickets that get resent every 9-11 months because they are closed with no response after nearly a year, so I just keep resending them. Not one has had a response since December of 08.
EDIT : Also, if it is a temp suspension, usually after a day or so, you will get a message when logging into the game stating how much longer the suspension is in place.
