Worst bank ever im closing my account

I deposited cash into my account at the atm and money didn't reflect in my account...went to the branch and was told they wil rectify within 24 hours , next day nothing is in I called the call center and I had to explain myself to each and every agent and get transferred and only after spending 80 rand airtime I was told I need to go back where I deposited the money , went there and they logged it in and was told I have to wait for 7 good days for the issue to be resolved and after 7 days there is nothing happening no fone call nothing , went into another branch to ask , the teller called the other branch and was told I have to wait for a call from that branch , bottom line is from calling them over 10 times I never received one fone call back and my money has not been refunded and I haven't been told anything just to wait till.they call me
