Very frustrating experience with Bryanston ATM and customer service

I drew money from Bryanston ATM. The machine didn’t give me the right money. I went into the branch and had to complete a form. This took over 30min. The got an sms with a ref number. No follow up on the status received. I went back into the branch 10 days later and sat for 45 min the bank customer service ladies indicated that there had been issues with that ATM and were surprised I hadn’t received a follow up status as they could see on the system it had been declined. They agreed that the machine was giving problems and that I should receive the money owed to me. They tried contacting managers and various people but couldn’t help. They said they would contact me. No response. I went back today 2 weeks later and while waiting for my number to be called my waiting number was skipped causing me to wait even more. There is no urgency and it feels like the faulty machine is more reliable than the customer. Even though I could tell the bank assistants believed my case they couldn’t do anything to help me. I have wasted SO much of my time (far more than the money lost). But totally infuriating that the system just wins and no one can help!
