How did they pay for them? Your feedback @ coinpayments have less the 20 transactions. As for answer to negative feedback - your site have "Wallet Setup" option - with import privkey or seed - which is necessary for card. Ofc it can be new empty address or dedicated for Equicex only, but "The system does not store any keys" can't be true.

Can your provide some real photo of card? Or at least cards BIN.
