I don't have a screenshot of the trade window or of the chat window as i had to restart steam because my internet was messed up, and as he blocked me i could no longer view the windows. I did copy a transcript of the end of the conversation, as far as it went up in the window before i restarted, though.

Trade was supposed to be as follows. My 1x Dragonclaw hook in exchange for $98 via paypal + 1x Mythical Silent ripper slark dagger.

Terms of the trade that were agreed upon;

I trade my 1x Vintage timebreaker for his slark dagger as collateral, so he knows i am going to go through with the trade, and he made himself seem very trustworthy.
He then should send me $98 via paypal.
I should then trade my 1x Dragonclaw hook in return for the Vintage timebreaker.

I traded the timebreaker for his slark dagger, i then asked for the $98 and he went offline and blocked me. So now I have lost my timebreaker. I have done this type of trade before and not had a problem until this guy scammed me.

This happened at approx 20:00 GMT on 18/06/2013.

Arti had asked to trade with you, but you did not respond in time.
Dondo Podge: oke
Dondo Podge: go
Arti has accepted your request to trade.
Dondo Podge: now $98
Arti: ok
Arti is now Offline.

I doubt anything can be done at this point because I'm not able to provide screenshots or proof of the trade deal. I'm just clutching at straws here really.
I shouldn't have been so stupid to trust people like I did, lesson learned anyway. Not sure why I believed his paypal screenshot either, it looks so dodgy, and is in a language i dont understand.

Without any clear agreement shown there is little to nothing we can do, we're very sorry.
