Worst experience

The worst service I have ever experienced I have been trying to close my credit card with them from Dec and every time I call them they tell me to pay +-R90 to be able to close the account which I have done just to find out my account is still active.

Whats more frustrating is when I tried to call today i need to approve my identity by accepting it on the app (Which i have not had in more than a year) to be able to just talk to a consultant. How do I go about closing my card FNB???
