Nedbank - no assistance with rectifying issue

I have called numerous time to try and sort out my overdrawn Nedbank cheque/savvy account. The issue is that I have made payment arrangements with Nedbank Credit Card to pay direct deposits but have still been debited from Nedbank credit card on my savvy account, as a result have incurred bounced debit order fees as their is no money in the account - hence why I pay direct deposits.

I am not winning with trying to sort this out with Nedbank.

I would like the bounced fees to be reversed so I can settle the outstanding monies owed in order to close this account.

Please help!?
