I bought a visa cc with a 4 digit cvv from base Feb#26_US/MIX_(RUBICON)_[SQL/Firsthand
I checked the card showed live 00 approval,contacted support for refund and they declined saying “checker show card live no refund possible”
But how does one use Visa card with 4 digit cvv and how does checker show live if cvv is 4 digit.Checker result must be DECLINED CVV2
