ANGRY NEDBANK CUSTOMER

I am so disappointed in the services of Nedbank. I was a victim of ATM *****. I have 2 separate claims. The first claim is for an amount of R5000.00 that a withdrawal was done but no money came out of the ATM as the ATM does not allow you to withdraw R5000 at a time only less. This had to be resolved within 4 days. I called on day 5 and my case has still not been touched or processed. I would have received a call back with an update but it never happened. I had to do another follow up call on day 7 and still no escalation. I went into the bank in Atlantis were i was told that my claim has been declined as they believe that the R5000 was indeed received at the ATM. I requested that the ATM footage be viewed as i have a case opened at the police station as well for the second claim where ****mers were caught on camera freezing the ATM and i could not get my card out of the machine and somehow they managed to withdraw or transfer R5500 from my account. Referring to the second claim i have not received any feed back at all its been 19 days this took place on the 26th Feb 2025. Could someone please advise on what steps i should take next as I cannot afford to lose R10500.00
