Terrible service and not willing to listen to problems.

I have been struggling for 7 and a half months to get my business account sorted out. I am a sole trader. I have got a personal account and a T/A account for the business. I get thrown from one person to another, some try but most of them obviously do not have the knowledge to help. This morning I was told by the local branch manageress that they were not willing to discuss a certain problem I have. I have been with Nedbank for most of my life and have got an excellent credit rating. I have tried contacting the call centre but get no response.
