NEDBANK JUST WANTS TO ***** YOUR MONEY!

In last week I phoned Nedbank twice to get a settlement on my credit card. The first time they gave me a settlement amount and I told them that I will only be paying the Friday and they said its fine. Then I phoned again the next day just to make sure the settlement was still the same which it was not... R300 more. I settled the account on that day and still sent proof of payment and email stating that I would like to close my credit card with immediate effect! And I want proof that account has been closed. They rep**** saying that I need to phone to cancel as they need to record it, which was fine. When I phoned to close the credit card, they said that they cannot as I need to pay additional admin fees that was added on that day of R27.00 Now, I cannot close the card as they want their R27.00.... what for??? They are the biggest corupt bank I have ever banked with. And then they still want to know why I want to close my credit card with them? I would like Nedbank to reverse that R27.00 and to CLOSE MY CREDIT CARD with IMMEDIATE effect! I am not giving you another cent!!!!
