We regret to inform you that your debit card is locked
When I called the number it prompts me that to input my credit card number. I was able to get past with card numbers generated from https://www.bincodes.com/random-creditcard-generator/
I put in garbage for everything else & it was accepted. The final message that I got was "your card has been reactivated. Thank you for your time"
