False advertising

On the above menshioned date I went into the ladysmith pick n pay to purchase some chocolates that was advertised. It was the cadbury slabs 3 x R25.50. I took the chocoates from the promotional basket ( cadbury caramel) on the sinage of the basket it had all slabs besides bubbly at that price. When I went to the cashier to pay the amount I of the 3 x chocolates came to R36.95. When I inquired they said that chocoates are not advertised. But if its not why did they put a whole lot into the promotional basket and when I came home I saw in the ad that the cadbery caramel was on promotional. The cashie called the supervisor and I was told to take something else or leave it. Very incorpontant of pick n pay. For falseLy advertising
