I have just got my UOB TX debit card a few days ago. The
acknowledgement slip is sent as well. But when I tried to add the
card to my PayPal account, it gave me this error:
This credit card has been denied by the bank that issued your
credit card. For details on why your card was denied, please
contact your credit card issuer's customer service department. Or,
you may want to try adding a different credit card.
I have googled this a few days ago and saw a topic about another
user experiencing the same problem. But the bank pushed the blame
to PayPal and PayPal did the same, back and forth. Any idea what to
do about this? And can anyone who has successfully added a UOB
debit card to their PayPal account share your experience
here?
PS.
I just did another google search and out of the two relevant pages,
two were posted by UOB debit card users.
