Game Vaal Mall not giving discounted items at sale price, but demands full price.

Game Vaal Mall not giving discounted items at sale price, but demands full price. The biggest of these items was a Jumbo Rubble Action Pup that had a sticker on specifying that it is marked down to half-price and it was also placed in the clearance area. I double checked the price at the information desk and the attendant confirmed that it was marked down from R229 to R115. After paying I checked the slip and saw none of the items I found at the discount area were given at sale price, I proceeded to customer care but they refused to help, after which I rather opted for a full refund for the entire purchase due to unwillingness to give items at discounted price.
