Service championship nightmare

I made an online enquiry and a consultant call for a new account and the consultant took me through the application process over the phone and later advised me to go to the bank with my ID and proof of residence. I got to the bank in Aucklandpark and the service championship directed me to the wrong queue which I was on for 45 minutes. She was so rude that she wanted me to join another queue and when I told her that it was her mistake she was not bothered to assist and insisted that I join the queue.

My problem is this is a new account that I'm opening with nedbank and is this how they treat their customers.

That service champion lady from campus square needs to be removed in Front as she does not have the patience for people.

I left there without being assisted.

This is very concerning as this is the only nedbank that is close to me and I'm not sure if I should proceed with opening the account and switching my salary.
