Horrible Customer service, staff without knowledge. Bad call center customer service

today I went to Fox street branch to sort out my Nedbank app which has a problem. firstly the waiting period before you can be helped is just too long. I waited for 2 hours before my ticket can be called. There are lots of staff members who are going up and down but service is horrible. I am even thinking of changing the bank. The staff are not informed, they can not assist you with a simple query. They could not help me with my app after waiting for two hours. When you call the call center there is a problem with communication. the other person can't hear you on the other side. I have spend the whole day trying to solve my issues without any luck. I am frustrated because if I can get my salary, It will all go to the beneficiaries that were supposed to be deleted on the bank app. This is frustrating, they don't even do a follow up to see if you have been helped.
