Because I trusted him as I worked with him in the past a lot of time.Where did you find this guy, and why did you not use something like odesk or elance, or even PayPal where you could get the money back so much easier.
I think you can file a dispute, but that's as much as you can do.
Can't sue him somehow? In real life I mean,i know some information about him.
I am asking this because I have only skype conversationas proof.
