This really sucks. Sorry to hear it. Not too long ago a forum member also got scammed, and while it’s notoriously difficult to get problems resolved, they actually were able to get a refund (as in, Buyee refunded them). Don’t know how likely it is, but maybe a starting point if you want to pursue this. Whatever happens try not to let it affect you too much, though that’s easy to say when it’s not you.
