False advertising 😒

I went to pick n pay protea glen mall and I saw nescafe gold coffee packed with a price of R109.90 and I took 2 bottles. When I went to the tills the product scanned for 179.90. I told the cashier that I saw the coffee for R110 and she called the manager who said that the coffee was put on the wrong place and did not seem interested in helping any further.. Isn't this incorrect marketing to lead customers astray and to confuse customers? I took pictures to show how the products were packed and its not only one or 2 products but a bunch of neatly packed products but with wrong pricing. There's a flier showing the special for R109.90 and it was also advertised on tv.
