marriioo is a scammer

i was selling my account to marriioo and this is what happened.
i got him to post on my thread, pm me with all his details, then i verified the account and gave him my runescape account + password and he wont send the cash(after we already agreed on the process) untill i gave him more info(bank pin + details) so i am pulling out of the trade and he is logged on and changed the password and wont give it back and will not withdraw or pay.

Chat logs are not proof, sorry.

 

there is no other info i can give apart from the post he made on my thread, the pm he gave me and the msn chat logs, this is a account trade not a item trade so no screenies could have been taken.
the only proof i can give is that he has my acc/psw and is currently on it and has changed the password and isnt giving it back and no payment.
if that doesnt do anything then dont worry about it.
thanks.

 

Permed.
