Nedbank poor client service.

Nedbank has the worst customer care system I have come across. For the third time now I used their Cardless withdral option. As soon as the machine starts to process the transaction and suddenly it gives a technical error message but by that point the money requested is debited from my account. On March 19 I did a Cardless withdrawal of 2000rand and again the atm did not release cash. I then logged the complaint and was told its a technical error and the funds would be released back to my account within 72hours. 7 days later I'm still sitting here with 3 reference numbers over the past week and each time I've been told the reversal was done back into my account and that there is nothing further they can do. This is a professional clients account transacting more than a 100k a month but they don't even have the courtesy to call me bk. Even my so called private banker. I'm just waiting for my reversal and I'm moving my business from them. I'm truly disgusted. S P Madlala ***
