Abysmal service

Nedbank are changing their App. and have warned clients of the shut down of previous App. on 12.11.2020. I have down loaded the new App. but incredibly it does not link my account. So on the advice of their call centre I went yesterday (29th Oct) to my nearest branch - Randpark Ridge - to ask for assistance. After 45 mins in the branch and having consulted two different staff members I was informed they were unable to sort out my problem ! It appears the only option I have is to close my account and take my business elsewhere ?
