Account scammed through Sythe

This morning I made a post selling a level 82 ruined pure asking around 60m. I was contacted in my messages saying he wanted to buy the account through paypal and turn it into a dharok pure so I thought nothing of it considering i could just use the money to buy gp. I have proof of emails, messages and proof that I own the account.
