Standing in a queue for more than 4 hours

I have experienced the worst service ever at Nedbank Jane Furse Crossing. How on earth does a bank combine Tellers and Enquiries in one queue? I stood in this queue since the bank opened in the morning. It's now 13:10 and I'm still standing in the same queue. Can somebody fix this rediculors mess please? This is real nonsense. Please separate the queues so that people who came to deposit only can just do that and go. Why do I have to spend the whole day in a bank waiting just to do a deposit?
