Standard bank i want my money.... Fix your ATM

I attempted to withdraw cash from Standard bank ATM at the Netcare Parklane Hospital in Parktown , But the ATM did not give me any cash or the receipt. I received sms notification that I have withdrawn the money and when I check my bank balance the cash has indeed been drawn. I phoned the Standard bank call centre and I was told they couldn't help me, therefore I must take it up with my bank(FNB) This ATM has been reported faulty on numerous occasions and everytime the technicians claim they have fixed it. It has been such an inconvenience that I had to log a ATM dispute with my bank (FNB) and I can only get a responds in 5 days time.
