Not my fight, but since they have over 700+ rep, I'd say you're overreacting here (threads like this aren't allowed) and you definitely overreacted in their thread.
Maybe try a little patience and allow them time to get back to you.
what if you was in my place ? would you not be pissed off that someone ripped you off ???
What I'm saying is that reputation does mean something. You don't find it hard to believe that a trader with that many positive trades would choose you to scam for a dollar? You don't think that maybe something else, like miscommunication, is going on here?
Edit: You said he unfriended you, which doesn't even appear to be true. A sudden disappearance can be a cause for concern, but the answer isn't always "scammer", especially with someone who has that kind of rep. Any number of things could go wrong, from a bad internet connection to a crying baby (been there). It's been an hour since you initiated the trade. That's not nearly enough time to play the scammer card, in my opinion. You already started swearing at him in his thread and left negative feedback. A big overreaction.
I know him and I'm sure he is not a scammer.
I guess he did not realize you made the payment.
Don't worry, next time he is online everything will be OK
So i added this guy for trade, i was interested in buying GRID 2 from him .
I offered him 1.20$ via PayPal . He gave me his e-mail and i sent the money . I waited him like 10-20 minutes, after that he is saying if i still wanna buy the game to let him know, then he unfriended me .
10000% sure that i didn`t trade with impersonator, because I added him, not he me .
