Settling credit card with no luck

I have a credit card with nedbank. I have been calling for the last month or so to get a settlement amount in order to settle my credit card. no one has been able to help me. all I get is a cold `There is not settlement amount for credit cards` This is ridiculous. How can there be no settlement amount for a credit card, cash payment. I do not want this credit card anymore, I need to get rid of it. I refuse to accept that there is no settlement amount. Can someone competent please call me with a settlement amount as I would like to settle this credit card yesterday already. I will not accept that there is no settlement amount. I am wasting a lot of airtime and money calling to settle my account, only to get the same ridiculous answer. Is this the kind of service nedbank offers to their customers? why must i waste my time, money and effort trying to settle a credit card I don't want anymore because of the lack of customer service and still get such a response. I will be waiting for a call with the settlement amount.
