Price

Good day, I have a really urgent complaint, I went to pick n pay in golfpark, meyerton. I buy every day at that place spending R1000 daily. Today they have this special on their liquid fruit juices x 6 for R29.99 when I got to the till they scanned it as R58.99 so the teller went to check and confirm it is R29.99 marked on the shelve. They called the manager who refused to changed the price because the bar code is different than the special one. I give a damn, no one shops at any place and asked to please check the bar code to see if on special, you check the shelve price and the law say what the shelve say they should give you the price. The attitude a manager should have to refuse to change the prices after they are wrong is really very bad. I spend maybe R12000 a month at that shop, but they will lose my business sorry, for not my problem if they can not fix their systems. They should give me the price what is on the shelve. Bad very bad behaviour of manager....
