Bad services

Good day I had a bad experience at parow branch I took burgers and the price was R49. 99 on the fridge when I got at the till price was 79.99 so I went and took a photo of the price tag and showed the cashier so she called a supervisor and they called a guy at the butcher that gave me attitude and told me infront of customers that I must pay 79.99 while I have the price tag on my cellphone and fridge it was in so I waited for more then a half n hour to be sorted out what a waist of time bad service I won't shopping there again next put the price tags on the correct products I got a photo of the proof to show.
