CREDIT CARD SETTLEMENT

I want to settle my credit card and close it. I do not have a banking app and do not even receive statements for this card. I have been into the branch and they could not even assist me as I did not have the card with me but they can pick it up on my ID number but still could not assist. I have tried to call the service center but they won't transfer me to an agent without accepting the approval sent to a banking app THAT I DO NOT HAVE! I just want to settle this account and need the details of where to transfer the money and the process to close it but it seems FNB is quick to offer a credit card as I get calls daily but when you actually want to close it they do not seem to want to help.
