WRONG PRICING AND RUDE MANAGERESS

Never have I had such repeated bad service from one specific person, and I have just had enough. Yesterday I went to Dis-Chem Garden Route Mall where I went looking for a specific perfume When I got to the shelf I saw the price of R195..I specifically looked at the description the shelf's price tag and made sure it matched the description of the perfume. Seeing as someone opened one of the perfumes, I took the closed/sealed box of perfume and headed to the cashier along with the other items I was going to purchase. When the cashier rang up the perfume it showed the price of R245-I told her the price is incorrect, on the shelf it says R195. She called the beauty manageress where she proceeded to take the box of perfume and head back to the shelf. She came back and told me the perfume that was R195 is sold out. HOW?? If he price label matched the exact description of the perfume? She also came back with the opened box of perfume that was on the shelf and accused me (infront of everyone) of opening the box.Consumer Act states that the price displayed is the price the customer pays.This manageress humiliated me that I decided to leave all the goods. I'll rather spend my money elsewhere
