It's only natural that buyer's account is missing - you wouldn't want that cgtrader would leave it to scam more people, wouldn't you? On the other hand, it's a shame that cgtrader doesn't give you any notification about refund being made for whatever reason, i guess they just don't want to upset their users and prefer to handle this semi secretly, which i found is quite unfair.
Regarding scammer's country, i don't think that matters at all, you can get scammed from anywhere in the world - bad people are everywhere.
