Nedbank - Credit Card

I have been calling and sending emails to Nedbank Debt Counselling and Recovery Services to get my credit card closed. My credit card is in credit of about R1300, I sent emails from 17 of Feb to get someone to refund the R1300 from my credit card to my personal account so my credit card can be closed. I have been waiting for this action to happen so I can get paid up letter and get removed from Debt Review, Nedbank has not been helpful in this matter even after trying to call them and email them. Just received only auto response that Nedbank has received my mail and I should wait 10 days for refund, its more than 10 days now and still no Refund. Seems like I should close all my products from Nedbank because of this poor service I received
