misrepresentation of the bank by staff

I went to Nedbank branch Secunda on the 8th to inquire about an account I once opened. I was given a ticket number E106 and the time was around 16:29. Their were a few clients in the branch, but most of the service booths were empty and staff members walking around the branch. Only 2 consultants were working and the rest of them all were either walking out the branch or chatting with their colleagues. After 25minutes of sitting in the branch and after a few attempts of trying to complain? I was eventually helped. Maybe it is the kind of service u get from Nedbank, but surely the service is different from other banks. And staff members should attend to all the members in the bank before they can leave the branch to two consultants to attend to the rest of clients that were in the bank. Respect your customers as we were also from work and our time should be respected as well.
