Puleng the rude PnP employee (supervisor)

Very appalled at the service I got at Pick n Pay Vaal Mall by the Supervisor named Puleng, I had just paid for my stuff when I realized that c***** cheddar brick which was priced R87 had charged R119, I didn't even leave the store when I noticed the price was incorrect. Went to the cashier which she called Puleng to assist, that came to me very annoyed which was not a problem until she snapped and blamed me for not checking the screen and making sure that the price is correct, without any greeting or apology, that lady went on and shouted at me even when I was talking to her colleague and my colleague, she was so rude it was scary.
