FNB cancelation gone wrong

FNB come on guys. My wife has been trying for more than a month to cancel her credit card. It's getting out of hand how unprofessional these secure chat staff are. It's a simple thing, she doesn't want it anymore. She spoke to an agent that said pay the settlement and it will be canceled. We did exactly as instructed, that was in January we are MARCH now and have to chat again to a different imbecile we keeps on existing on a settlement amount. When there doesn't show anything is due on the account. And further more given all sorts of excuses and blaming the previous consultant who assisted us that they never closed the job so now they cannot do anything Can whoever is in charge of their social media arm of the company please show this to cancelations so we can get proper help. I STRUGGLED TO CANCEL MINE AND NOW ITS THE EXACT SAME WITH MY WIFE. It takes under 5 minutes if you approved to get a credit card, but it must take months to cancel it?
