I have a PO Box with USPS and there is a glitch in their online system that prevents me from removing my credit card on file and it will auto-renew on 8/15. I need to replace my good CC with a bogus CC so that it doesn't auto-renew. However, when I tried to input a bogus card #, CVV, Exp Date, Name and Address, I received an error message.
How do I find a bogus card w CVV, etc.. that the system will accept?
