Standard bank - one of the worst

Standard bank is probably one of the worst banks when it comes to customer service. On Friday a consultant called me as I did an online over draft application, she notified me that everything was approved, however, there is a problem with system so it will take 48 hours to clear into my account, today is Tuesday and I have taken time off work to go into the bank to see what has happened as 48 hours have passed, the bank knows nothing about this and on top of it all they won’t call customer care for me from the branch, so much for bank charges - we pay for these services they are not free!
