Nedbank has no customer service at all

A company called Central Finance debited my account with almost R3800, and as I am currently working in Cape Town, I went to the closest branch at N1 City to report this. After waiting for some time a consultant helped me. I explained the situation and the consultant informed me that they would not reverse the amount, as I had to log a case on the ***** site etc, and that would take weeks to investigate. I was getting annoyed, as my account went into arrears, because Nedbank do not have any security platform in place, I do not have an overdraft account, and this was the second time this month that my account went over the available balance! Nedbank just keep on charging cost, and it is definitely no use banking there as they do not care for me as a customer. The consultant put my card on the counter, and left me standing there. The manager, Elaine Strydom came to me, and told me not to be rude to the consultant, and told me to leave the bank, which I did, after I again explained to her what happened! I am going to close my account, because of this, which means because the bank doesn't assist the customer, I have to go through all the trouble of switching banks, switching debit orders, and a bank that doesn't accommodate me as the customer! I am furious to say the least.
