FNB services not working

Yet another issue with FNB.... I recently received my new card and after entering the card number and pin the message received is "Your request cannot be processed - Enter a valid card and pin number" I have done this 3 times but still receive the same message. I cannot use online banking to transact either because this requires approval on my FNB app which is not working. I do not want to phone FNB as I have no time to be transferred from pillar to post. Can someone sort this out?
