Barely a month old with the Bank and I am loosing money with no recourse.

I withdrew money from an ATM using the cardless service. On the 1st attempt the slip came out with "Can't process the transaction at this moment please try again later". I tried again immediately and the slip read "The pin has already been used". I logged the issue and was advised 3 to 5 days for a response. I called in to follow up on day 4 and I was advised the money was being sent back to my account it should be sorted. Day 5 came and still no money in the account, I called in again and to my shockthe feedback this time was that " Sir this was rejected as the is no surplus in the ATM". There seems to be little to no urgency to Nedbank to investigate people loosing money at the ATMs, the investigation process seems flimsy as it is Nedbank enabling ********s for them not to have cameras at their ATMs in 2023. I have not been a client for a month and this is the intro to the Bank. the customer service was slightly impatient, as any customer complaints consultant that is not trained to diffuse tension and empathise with the client that is investigating loss funds is inadequately prepared for the job.
