Very slow services and staff not paying attention to clients

So the past months was coming to nedbank mall of Africa after the 25 it always took time now is came today to fix my card I have been waiting for 10 minutes the bank is not full when I got here was the second person to enter and even now m not helped. I don't understand why there so many people but services is beyond slow. It's clear that they just don't care about their clients you just see staff going up and down. Something really needs to happen can't be served after 15 minutes when there is no question at all for someone who always talked highly about nedbank I am very disappointed I really feel disappointed. I feel like I was in the shopryt que.
