Horrible service and advertising

I wanted to buy a promotional stir fry pack at pick and pay canal walk, as usual the prices rang up incorrect, the manager was called (kayum was his name). They acknowledged it wrang up wrong but wanted to make many calls first to find out why the barcode was not updated while I must wait and let the story fry defrost. They also refused to give their own double the difference policy because it is 'promotional' which is utter nonsense. I will never shop at pick and pay again. Spar and Checkers never give me and issues like' **** and pay'
