Disaster customer care worst

Yesterday the 24th of September 2020 I went to go withdraw money and the ATM said insufficient funds I immediately called the call centre number who told me they could not assist because I was unable to be verified because my phone has to sims and can't receive the notification . I called again to the custumer care number and the gentleman told me that he is picking up in information from August were I put my money in the savings. He put me through to Vuyo who while hearing me out just dropped the phone. I am disappointed that Nedbank failed me and now I have to wait for the banks to open to go findout what happened couldn't even stop the account
