POOR SERVICE AT NEDBANK

I was at Nedbank church street branch the other day. I waited at the queue for almost an hour before going inside the bank. Later whilst inside I waited my turn to be called to the teller for my query. Two men with grey suits entered and they started asking bank staff passing about specific people they wanted help from. At some point the other one was saying only if they could get a Martha, all would be sorted quickly. After some time that lady Martha passed by and they called her and explained to her what they wanted. She told them she was going for lunch but she will try something quick. She went into the tellers who were busy and asked to use their machines quickly, and those tellers were helping clients. I happened to wait 10 minutes to be helped the teller who was supposed to assist me was busy with Martha and the 2 men in grey suits. I asked the white lady whom I did not get her name why did I have to wait that long to get help. She said she was assisting her colleague but I told her that those men came in whilst I was on the queue and why would they get preferential treatment to us. She said she has no idea what was happening, it clicked to me that the Martha lady might be a superior to the teller who was assisting me because when she finished she told a certain lady at the forex teller that she must help them and gave them instructions. People who were in front of those two men watched as the 2 men in grey suits got preferential treatment
