I saw your PM just now. First of all sorry that you might have gotten scammed. Secondly you haven't mentioned that you need to pay for some item with someone else Paypal, as you told in the PM. Since Paypal payments sent don't always go through due to billing address mismatch and other things.
For the scam issue I don't think the user will respond. If he wanted he would have done it within that hour itself. Don't go to deal with ranks here. People are selling accounts like cakes in the forum. Better to open a scam report so other users are safe. Anyways sorry again. I know getting scammed sucks. But you will have learnt a good lesson now.
