Failed to notify me of the charges incurred

I am very unhappy of the fact that. I went to Nedbank to pay and close an account that was overdrawn. <br> The lady who assisted me made me sign the forms and informed me that the account was closed. <br> A week later I received a message saying that my account was still overdrawn when I was under the impression that it was closed I went to the store and asked to speak to the manage r of which that did happen. <br> He assured me that he was going to deal with the staff member who assisted me and that he would close the account and write-off the debt and that they would call me in a week up to until now I haven't heard from the manager or anyone from Nedbank except that I received another message on the 10th of October 2015, Not sure why would a branch manager lie and say he will deal with the case and don't do anything about it?
