No help from business banker

Our company is a small business who have been instructed to bank with the Vangate City Branch because Ms Aziz is the only Small Business Banker in our area at the time. Since we Ms Aziz took over the account we have not met her once, can't get hold of her when we call and not once has she been able to help us with anything. I have been trying since Monday to get hold of her, called other business bankers all over the Western Cape and couldn't get hold of any of them either. I finally got hold of Ms Aziz on Wednesday and when I explained my problem she said she would try to help. I explained the urgency and that I would need an answer before Friday. I called her Wednesday afternoon to ensure that she got my document which I emailed to her. Since then I have not been able to get hold of Ms Aziz. In fact I even tried asking for the branch manager who was conveniently out at the time. I called the customer service center and they put me back to Vangate City where I was told the best time to contact Ms Aziz is after 16H00 in the afternoon. Is there anyone at Nedbank who is even remotely interested in helping a small business?
