Bad attitude from collections desk at Chris Hani

This incident happened today around 9:30am. I wanted to withdeaw or do a transfer from an expired card. I got the worst service ever at the Chris Hani Branch (Collections desk). While helping me the two female consultants show each other the monitor and they started laughing. I found that very offensive. I asked them if they mind sharing the joke. They said they were laughing at their own stuff. How rude. Next thing I ask how to create an Internet bank profile on my phone since I already have the business bank profile. She gives me some funny look as if I'm asking a stupid question. Instead of explaining she sends me the link via sms to my phone. I was so gatvol when I left. That's the worst service ever, but nevertheless I kept my cool. Some ppl don't deserve to be in the frontline, they're just tarnishing the brands image.
