Really had it with Standard Bank now

I had an incident this morning, withdrew cash at an ATM and it dispensed less than what I requested. I also noticed that those machines do not print a receipt unless you request one, now I know the reason behind it. Got back to the office and noticed the incorrect amount. Called the number on the sms and the guy gave me another number to call and transferred my call. Waited seven minutes and still no answer, the call cut and I called back a while later. This time, the consultant is even more unhelpful, saying that I've come through to the credit card division and would need to go to the branch to report it. Do you think I have all that time to run around due to your machine issues, further to that why give out the number on the sms if you cannot assist. I think I've really had it with Standard Bank and I'm very close to changing banks now. Mentioned it to my colleagues at work and was told that this happens often with Standard Bank. Starting to wonder how safe my money is with your bank. Think I need to change before anything serious happens.
