Worst customer service

I have an existing account with Standard Bank. I have tried to open a savings account on my online banking and phone app and get an error describing I should go in branch. I have called the call centre who cannot tell me the problem. I went to the Brooklyn branch in my lunch time and waited 45 minutes for help!!! I had to walk out as I was pressed for time!!! The staff were chatting in between clients with no sense of urgency. There's a reason its called Beep bank..pathetic!!!!
