Bad customer service

I'm suppose to collect my new cheque account at FNB branch. It's the first time going to the FNB branch as I am a new customer. I opened it over the phone as I was called by one of the consultant. I went today at 11:40 to collect my gold cheque account. The lady at the door told me to sit and wait at the queue. I waited there for about 50min. The queue wasn't moving and people who came before me were complain that the service is slow they've been there for about an hour now. Other were giving up and leaving the bank as the queue is not moving. Finally this other consultant Agner Ndlovu ask us 1 by 1 want we were doing there. She tells us to go wait in collection but there was no one there. Only to find out she is the one who is going to help us. I didn't get the whole thing that we waited in the wrong queue for an hour because the person who suppose to help us in collection was on lunch or something. There was no one to replace her. It's the first time I go to the branch and I got really bad service. The branch is under staff. I doubt if I want to have a cheque account with the anymore
