False Advertising/Failure to follow procedure

I went to game eastgate on 181215 to purchase a product that was advertised in the weekly express, where a 10inch 2for1 sinotec tablets were advertised at R1700 prepaid (NOT EACH). I approached a assistant named Blanche about the deal who took us to the shelve where the product was displayed,she then informed us that they were R1700 ea.I then showed her the pamphlet and she said she would take us to the information counter ,she then phoned for assistance and was advised that Joseph was in the front of the store. I then explained my story and was informed that communication was sent to the store on the 141215 regarding the misprint and that correct ad was to be displayed on shelve by this specific product, which in this regard was not actioned and was only given to Blanche when I requested to see when the correct ad was sent to store which was the 14th I was informed by the Joseph that he was in no position to make a decision and to call head office on Monday 21/12/15. I was also asked by joseph who would I like to speak to rather than advising me who to contact.I feel I should be given the deal as they received a corrected ad and failed to display even 4 days later.
