Ancient ATMs and Extremely poor customer service

I am a Nedbank Private Clients customer. While I am full time employed and earn a salary, I also have a small “side-hustle” that generates cash daily and I therefore make daily deposits at my local ATM. Over the last 6 months though, I have had more than 10 incidents where the ATM retained my money. These ATM incidents are extremely inconvenient as they often happen on Fridays or month end, making me unable to pay for orders or service my customers for days. It takes 4-6 working days to resolve each of these and my irritation is that, even if I am luck for Nedbank to check the ATM on the same day or next day after the incident, they will still hold my money and not return it until the full 4-6 working days have passed.

Over 6 months, I have lost use of my money for well over a month! Nedbank is destroying my small business.
