Silverton Standard bank go-slow and bad service

Today I received the worst service from Standard bank Silverton. I got into the bank around past 1 and only got assisted @ xctly 15:45,because apparently people that came into the bank after me, that got assisted before me, all had appointments... So my question is, should we all book for appointments to see costumer consultants just for surname change??

Some man even asked them why people are coming in and out when they found us there, I don't know what their answer was but he immediately stormed out of the bank.

I am definitely changing my bank, I refuse to wait for 2 hours to be assisted when I even initially found the bank empty. Their consultants need to improve their service for clients that might use their services in future!!!
