Nedbank refusing to close an account

I have been battling for months to get Nedbank to close my account. I have not used the account for 5 years, and Nedbank is refusing to close the account because it has a R100 credit. I don't have a card anymore and I don't have an internet profile. I cannot create an internet profile to transfer the money out without a card. I cannot withdraw the money without a card. So I wrote Nedbank a letter instructing them to write off the R100 and close the account. I received an email from a "Client Services Resolution Manager" on the 11th of January stating that the account would be closed within 3 working days. It is now a month and a half later and still the account has not been closed.
