scammed by Mathematician

I was selling my rs account :http://www.sythe.org/runescape-2007-mains/1773363-selling-main-99-99-86-cheap.html

and mathematician said he would buy so I gave him the username and password, and changed the email to his... he said he was at university so it would take time to pay with western union. I messaged him multiple times and eventually he stopped responding to me, and I check his threads posted and see hes trying to sell my account for rs gold so that he can make a quick profit before I recover the account.
