No feedback for months and calls NEVER answered!!

Have you tried calling The Standard Bank Overport City branch? The Customer Call centre had tried to help me get through to them in the past four months and not a single call transfer answered. I have my Telkom itemised billing to prove my point. In March 2015, I realised that Standard Bank was charging me exorbitant bank charges as an error on the part of one of their Consultants. I was reassured that the Team Leader at Overport City will call me back with response and account rectified. Twice I had gone into the Bank and waiting in long queues and both occasions I was told that he would contact me. It is almost August and still no feedback. I called Customer Services and they say that they cannot find any query notes on my account even though the Sales Consultant added notes onto the system in my presence! Standard Bank Overport City is one of the worst service providers I have come across. The Branch Manager is never accessible even when you request to see her!
