HORRIBLE CUSTOMER SERVICE AND DISPLAY OF MISLEADING PRICING ON GOOD

I bought C***** 180g cheddar sliced cheese at PnP The Crossing in Mafikeng, the price displayed was R26.99. I even varied with one employee if indeed it was the price. When I got to the till the price was R29.99 which I queried, the teller (Sinalo Ndamane) and one other employee were rude upon querying the price. The other employee went to the deli and upon her return she asks me "why do you say the cheese is R26.99 when there are so many prices displayed there" I told her it's was written there with the full description of the product. She said I was lying. We went back to the deli and I showed them the price and asked them where was the R29.99 price on the display and it they couldn't give me an answer because there was no such price. Out of no where a lady working inside the deli produces a price she had her. Both employees at where rude as hell and didn't even apologise for the inconvenience, instead I was told by both of them that they are not employed to price goods, either I buy the cheese or leave it. That Pick n Pay has a tendency of displaying incorrect prices and it's employees never take responsibility but become nasty when one queries the pricing.
