Bad waiting time

I went to Nedbank New Market Mall today, the second time going there for bankstatements and my new cards (which I also had a problem ordering) I only have 30 minutes lunch brake but I have to wait in line 15-20 minutes for someone to see me then still explain to them what I need and wait for it. Still I dont have my statements or my card because I cant wait that long. My sister is with FNB - she went there to get bankstatements. 10 minutes and she was out and happy with the service. They have kiosks with pc's where you can print your own statements they quickly stamp it and your done. All I can think of is that Nedbank doesnt have enough staff to help everyone. No one wants to wait that long to be assisted. I will be joining FNB shortly*
