I have been having trouble adding my AMEX Virtual Pay to my PAYPAL account. Whenever I complete my Add Credit Card information on Paypal and click "ADD CARD", I get a message saying "The bank that issued your card didn't approve this transaction. Please contact the card issuer's customer service department if you have any questions. Or you can add a different card now to continue."
This is giving me a headache. I am done with KYC and I have credits with GCASH. What should I do?
