Briefly explain the trade: Was selling him an account. I went first seems an okay guy. Gave him all of the details to the account changed email password etc. Said he couldnt log on the account as he had a problem with his computer. So i was like okay. I feel worried that im being scammed, he then goes offline and doesnt reply to messsages or pms on sythe eve thought he is online.
How they scammed: See above.
Proof that you were not talking to an impostor:

any other proof required please contact me. He has since changed the ingame name on the account so i know he can geton it and that he has scammed me

 

can someone look at this please?

 

found out the buyer had given me an incorrect email address when changing it so it went to someone else. Contacted jagex and they have manged to remove the email from the account allowing me to get access to the account again im now trying to sell it to him again
