Nedbak service is schockingly bad and their consultants rude to their long term customers

Nedbank credit card division is useless! NOW THAT'S DIFFERENT because they refuse to close accounts, keep on charging monthly fees and are rude to customers. I have been trying to close my account for a month!. I am being promised that it will be done in a day or 2 but nothing is done. After 6phone calls, the last agent rudely put down the phone after I waited for 5 minutes to be attended to - due to large call volume. The service is shocking! I have accounts with the 5 main banks in SA - Nedbank is by far the worst in services and dealing with clients.
