Standard bank again

My wife tried to pay in R3700 into atm at rondebosh and it swallowed her money. Ok it happened and my bank makes a note and investigates and returns the money. Not standard bank. They make you go into branch then tell you it’s not their problem but a central atm controller. Don’t have the contact number and will not deal with your problem. So what do you do??? Genevive at Rondebosch exceptionally unhelpful. Eventually used the excuse my wife said a bad word so would not speak to her. Wow excellent PR strategy.
