I am struggling to understand exactly what has happened here.
Right, so he is accusing you of being a scammer.
Why are you posting this thread then? Just leave him adequate feedback on his trust page, and move on, unless you got scammed yourself.
If that is the case, please provide evidence of this using the correct format, which I will quote below for you.
