Day light ******* and False Adverti*****t

Day light *******, I went to checkers hyper (Flamingo) and as per their adverti*****t they displayed items on special when you purchase using their checkers card , I did exactly that and to my surprise when I got home they items were not discounted. I am livid as this is not true reflection of the prices we see. I would like to be reimbursed as I would not have purchased these items if they were not on sale. I have the slip and I remembedr which items were on promotion . I am so mad as this tells me that I need to wait and check my slip before leaving the store. so disappointed !
