Banking machines don't work properly

Basically every interface Standard Bank has fails me on a regular basis. Today particularly again the ATM cash deposit service. This is the second time in a week that their machine swallowed my cash and printed out a paper saying I have to go to the branch. If Standard Bank advertises a certain service they need to make sure their machines work. Now I have to wait for a technician to come out and open the machine to give me my cash. At Nedbank and FNB an ATM deposit works and it happens within 30 seconds. Why is everything Standard Bank offers a struggle?
