thank you all for the replies
I admit I made a mistake don't know why didn't look at his trust , probably because it wasn't negative and the account being old, I am scammed here on bitcointalk for the second time :-(
as for screenshot, accept my apologies, I actually took those with my mobile, had some strange problem with my windows, it's hanged as soon as I press prnt scrn.
as for chatlog, I can certainly give it to you, though, the seller, just blocked me instead of saying anything, and is not responding to my pm, perhaps anyone senior can pm him and ask him to come to this thread and talk to me one by one.
once again, it's 99% my fault, that I didnt' check his trust rating where a clear warning was already shown. :-(
I have left him negative trust.
Karma is a bitch, scammer.
Scammer whining for being scammed, this is the irony of life.
