Pick n Pay is getting worse

Why can your store NEVER get the prices correct - I complained about this a couple of months ago when a new manager joined and nothing has changed. The prices advertised on your shelves do not match up to the price charged at the till. I bought a single fitted sheet on sale that was advertised for R80.00 and when I got home and checked my till slip, it went through at R150.00 The same with the KitKats - 3 for R25 when I checked the slip, it was 2 x R15.00 and 1 x R13.99 No wonder so many stores are closing down. People will prefer to shop elsewhere because you just can't get it right. Now I have to travel back to Steeldate tomorrow to complain and get reimbursed!
