@Rysofly2000 Are you updating your payment through the App or Website? I would try both methods if neither of them works my suggestion would be to open a Support Ticket or private message CS_Agent for assistance.
@Rysofly2000 Needs to be a visa or visa debit . Not a regular bank card . But to many failed attempts and you will need to wait one full hour and try again incognito private mode or on the new PM app even
Add worst case you can ask support to update it for you also
