... Basically what happened here is that you sent a payment directly to the scammer. Coinpayments doesn't actually control the keys here.
Basically if I had not been misleaded by the coinpayments.net payment gate (and as an ordinary person I had the right to think that the participation of a third party is primarily necessary to protect the transaction from fraud and not just for technical convenience of shop's employees) I would have never bought anything directly from those damn scammers
I hear that. But personally I'd have never gotten involved with such a scammy sounding site. Even if the deal were escrowed, you're bound to experience some hassle at least. When it comes to mining hardware, you should deal directly with the manufacturer. The chances of being scammed are very high.
I don't think Bitpay or Coinbase offers any protection in this context, either. They do refunds, but only as coordinated with vendors. If you get scammed by a vendor, I think all you can do is file a police report...
