BAD CUSTOMER Experience received.

I was at Dischem in Mondeor, I wanted to buy Lipsano the online a tube,the price tag says R119,99.When I get to the cashier to pay,the price says it's R149,99.I told her to ho and check the price and she came back ,it says R119,99.She told the supervisor, she said customers change prices,I can't have it for the price,I saw it advertised with.So the supervisor chose to accuse the customer instead of dealing with whoever who packed items and put a wrong price. I was so disgusted by the behavior and attitude received at DISCHEM MONDEOR today.Customer service from the SUPERVISOR,by the CASHIERS is appalling.
