Terrible customer experience at pick n pay pavilion

Horrible Customer Service at Pick n pay Westville Pavilion, they put wrong prices at the shelf and the product scanned a different price at the till and I told the cashier that no I am not paying I will pay the price that was on the shelf then the cashier called the supervisor who went to call the manager and as she was telling him what happened I could see she was telling him to come and tell me that they will not sell it to me even if it's their mistake to put wrong pricing and manager shocked his head and said no we not giving at that price ,then he came to the till and Rudely asked me what is the problem very loud as I was explaining that the product is scanning a different price than whats on the shelf he kept on interrupting me telling me they will not sell it with the price on the shelf, he did not even go to the shelf to verify or check if the price was wrong on the shelf meanwhile the whole shelf was price wrong, will never shop there or even recommend anyone to shop
