Disgruntled customer

I am very appalled by the service I reached from Nedbank after I opened a ***** case with them. I am disappointed with the treatment I was given as an elderly person as I had to run around to get help after losing so much money. I was at the Engen garage ATM in Tokoza on the 10th of April, As I was withdrawing, there was load-shedding and my card was then not returned due to the load-shedding that impacted the ATM. I did not receive any money either. I was withdrawing R4000. I tried calling the helpline on the ATM but didn't get through due to network issues because of load-shedding, I had to move away from the area to get better network Coverage where I called my daughter who called in for me to get the card blocked. When I went to the Nedbank branch in Lenasia Ext 1 as I was working around there on the 11th, I discovered R9000 was withdrawn from my account. I opened a ***** case at the police station case number 121/04/2023. The ref number from the bank was ***9 which was then referred to the ***** department and the case number given was CPT-49042, which outcome was that I compromised my pin. How did I compromise my pin if my card was stopped and not returned by the ATM and the withdrawal was done in different places from where I was withdrawing? I feel my case was disregarded and I have spent months following up only to be given such a response. I was just dismissed with an excuse, I have been banking with Nedbank for years and I really expected better treatment than what I received.
