False advertising

Had the worst experience at Pick n Pay Hyper Princess crossing today. After shopping took my kids home and headed back to buy my son his Christmas gift. It was a ho er board I spotted priced at R1999.00. Got to the till and was told it is R3999.00. After telling the cashier it was the wrong price I took her to were I had found the item and she confirmed there was no price of R3999 on the shelf and there was a special offer sign of R1999 and a second smaller tag with R1999. She called the supervisor George who simply told me that the price is R3999 and regardless of the advertising price that is what I must pay.
