False Advertising 2+1 free special

False advertising in their 2 + 1 free deals. I went to Dis-Chem today and they had 2 + 1 free deals on their Always Pads. The sign on the shelf says any Always product however when I got to the till I didn’t get the discount because they said I can’t mix the 3 Always products they all have to be the same. This same issue happened to the customer at the till next to me with another product that they were also buying. The cashier supervisor on duty at the Dis-Chem Meadowdale at the time of my purchase absolutely refused the discount. Even my cashier had checked the pamphlet with the special and it didn’t say that we can’t mix the products.
