Staff unwilling to help

I went to the brakpan branch wanting to make an ATM deposit into my account. As a arrived the one ATM was available and I went through, as I approached I saw the Deposit function low lighted. I then stepped back and waited for the our ATM machine. That guy was busy for very long so I waited between 5-7 minutes. finally I approached the machine and the deposit function is low lighted. I then went into the branch filled in deposit slip and went into the queue. Waited there for probably 5-7minutes before assisted and I approached the counter, I explained to the lady the above and asked her that because I get one free atm dep per month please can they reverse the charges. She checked with her team leader and said they cant. I told them that yes they can, tomorrow after the charge has gone through they can reverse it. She asked me for what reason and I said because the ATM is not working. She then said to me that they are fixing the ATM's I must just wait 5-10 minutes then I can go back to the ATM. I explained to her that I am 38 weeks Pregnant and have been here for almost 20 minute now for something that was suppose to take 5 min. She still expected me to wait. I left no dep made.
