Very rude cashier and security guard at Shoprite Kaalfontein Corner.

I went to kaalfontein corner Shoprite this afternoon and the experience I had with a cashier how had the worst service.She was very rude and didn't not have any remorse when I confronted her regarding her conduct towards me.The security guard the proceeded to be very rude and did not want to listen to my complaint. I did not manage to get their names but I am really disappointed in their service or lack of.
