Product keys bought on g2a

How do I go about, exposing these thieves for the criminals they are. I mean I bought a product key from their site, .. seemed like a good deal.

However the key never worked, so put in a claim, with g2a and paypal, paypal refused to give back the money, and g2a only wants to give back the money if I provide a good review for the product.

However I'm not willing to provide a good review so others kan get entrapped in this scam.

And paypal claims the product was deliverd so, not getting back my money ! I would like to ask adobe if they can verrify what is wrong with the provided key. So I can file a police complaint, .. to be honest I think Paypal is partely responsible, for helping the scammers.

But I don't see a way how I can contact adobe about something like this. It's not their problem, I understand. Still getting rid of these kind of scams is a win all together.
