Useless consultants

I have been phoning African Bank for two weeks straight now and every time I have to explain the whole situation to the new consultant because they are apparently incapable of making notes on the system. I want to settle my account with them and I need conformation letter from them, which was suppose to take 48hours. It has been over a week and a half and absolutely nothing has been done to assist me. They are clearly incapable of assisting clients in even the most basic matters. This is unacceptable and absolutely pathetic!
