Sportscene Zebediela Plaza wrong pricing

I was trying to purchase sweatpants at Sportscene Zebediela Plaza that were on 50 percent which the original price was R 399.00 and the cashier was so rude when I told him that I’ll be paying what I’m seeing on the price tag his excuse being that the pants are no longer on sale… he was not trying come up with a solution but rather telling me that he’s not going to help me it’s either I should pay the for full price or not buy at all
