You may be a newbie but your account is 4 years old and you have a nice green trust rating there. Why did you allow him to talk you into paying first? This is why scammers continue to operate with impunity. For one, they know they can open accounts every 2 days and misuse it without fear of being sanctioned. Sanctioning them (tagging them) has little to no deterrent effect because they can open countless accounts here and use them to steal brazenly.
And the conversation flow on those chat screen shots... there is such an arrogance and control in the way he leads the conversation. I would have called him out and stomped on his boundless ego. Why did you allow him to talk to you that way? Pay for $250... minutes later, no $250 so pay more. Sorry, no refunds (even though I told you I do have $250).
Escrow always. If these scammers say no, decline to proceed and report them. Waste their time.
