first, you got to see if the card is not dead. Easy ... make an netflix account or some porn website to register for a free trial. Some sellers on Empire will sell you some dead cards, it's part of the game. So everything went good, next with your burner phone call the banks to find the balance (you should have all the infos to when buying the card).
Now you know that the card is valid and the balance. Here's your mistake, you only used a vpn. That's a no no. Most website will block you went they see it. You need to set up a Virtual machine and call it computer of "name of the victim". Change the time zone of your virtual machine to the same as the cc owner. After, with a combination of RDP/VPN and SOCK5 (check that the ip is not ban) it should go. Finally, go check if your 100% anonymous (this is federal time ... don't forget it).
PS* First purchase should be 200$ max and do it in day time. Also, stay away from buying bitcoins, gift cards are easier ...
Good luck!
