Account Suspended - Ultra Lord's Gift Shop

My account was suspended on GameFlip for trying to sell my Runescape 3 account. I genuinely did not know you couldn’t sell accounts as i see them for sale all the time. It was an honest mistake and now i know. Is there anyway I can get it undone?

Hello! Please, send me via PM your invite code so I can check it and give you more information?

Thanks!
