Disrespectful and rude staff!

Pick 'n Pay, Summerstrand must surely be the worst of the franchise's stores. Issues over the years are just too numerous to list. Today I purchased the Nestlé 5 for R42. The cashier scanned the Smarties at R10.99 each. I queried at the front counter and was told the promotion doesn't include Smarties. So back to the shelves I went to fetch the price indicator. She then (very reluctantly, and without apology) shouted for Portia to help out. I was eventually refunded R11. When I queried the amount and indicated that it should be R12.95, she again shouted for Portia. They then both wanted to argue with me, which is quite laughable as I am actually a lecturer in Mathematics. By this time the queue of other customers with issues had already built up to such an extent, that I just took the R11 and left. Your staff are rude, inefficient, uninformed and disrespectful!
