Price mislead

On the 17 Dec 17 Bauer 28 cm ecomotel classic pan had a special price of R129 on the shelves and when I got to the teller the price was R299. When I tell them that the price is R129 they told me that that price is for something else, which was not even there. According to them the pan was R349, it went to R299. Then I went to Pick n pay, only to find that the normal price of the same pan, still under Verimark is R299. ???
