Bad Service

I just received the worst service in checkers harswater! Half of the products on the shelf has no prices and when we finally got to the till the display that shows you how much each item is wasnt working so we had no idea how much we were going to pay and then when it was time to pay the lady said the amount due is R800 but she tried to swipe our card for R1100. When we asked her why that is she couldnt give us a straight answer..... that is a big gap in price differance, worst service I ever got at checkers! I will not be going back there again.
