Pathetic Client Service!!!

The Colgate herbal toothpaste had the pricing R6.39. However when I came to the till according to the system it was R8.99. I advised the cashier that the pricing on the shelf indicates that the product is R6.39. She went to aisle where the toothpaste was and confirmed that the amount was indeed R6.39. I was told that it was the wrong barcode and that I had to pay R8.99 which wasn't indicated. I called for the manager, Mr Bakr Rylands and he said that I have to pay R8.99.He had such a stinking attitude and was not trying to be accommodating at all. I am disgusted with the service I received because if it were at any other PNP I would of been allowed to pay the price that is indicated. This is the first time I have receive such poor service from PNP! Really Pathetic as I shopping at Pick n Pay regularly.
