cheat? or real?

yes he just scammed you sad

you will ask refund Else open dispute to paypal

You are being scammed.

Yes, looks like cheating. Better to ask a refund soon.

Yes mate.

You’ve been scammed, and for a hefty amount. I wanted to ask where you met this seller, but judging from your answers I conclude that the mediator (person or website) was not entirely reputable. If it were, you’d likely have made attempts to get your money back by now.
This is unfortunate, but it does happen. The best piece of advice that I can give now is to treat it as a learning experience. Next time, check someone’s reputation before buying from them. Good luck.
