Shiest is a scammer.

Briefly explain the trade: I purchased a runescape account through paypal, I have disputed the payment now and they will recieve a fraud infringment.

I looked up the account and confirmed the details.
How they scammed: They supplied me with a different account to the one specified.
Proof that you were not talking to an impostor: It was his username and real name on both msn and sythe.

You need proof you weren't talking to an impostor - Link to a post made by him with his MSN.

 

Or report any PMs which link him and his email.

 

Nevermind - Banned.
