You wont pay what you on the shelf at makro woodmead

I went to the makro in woodmead to buy the chateaux cheese cake box around 17:20 on the 11 january 2024. I went straight to the chateaux fridge in the makro store only to get the cheese cake box cake that was priced at R245.95,the sales man at the cake aile realized that the cake were priced wrong and he quickly said oh no mam sorry the cakes are not that price it was a mistake .i was but as a customer i have to pay what i see on the shelf. He quickly removed the wrong price but i had already taken a picture as he was removing the price. So i got to the till point the cake scanned R550 i was told no u have to pay the right price and not what you saw. As a customer u must also check the tags (as if i know thier codes) so this lady named Rethabile supposedly the aile manager then tells me she has to investigate first ,she cant just give me discount. After all the effort i left the store without the cake . She was very rude on top .
