Lack of pricing due diligence - Pick n Pay

Once again PnP Faerie Glen has failed to disappoint by overcharging me nearly 250% for a 1L bottle of Orange Juice. These bottles, which I buy almost daily, usually retail for approx. R30.00 plus change. Imagine my surprise when I noticed at home that the charge was suddenly R119.99. I have to ask management, where is the due diligence and oversight when pricing items? Are your staff so jaded and disinterested in customer service that they impetuously carry out their tasks? As a pensioner (and, of course, in general) , I really expect PnP management to implement effective supervision and have some form of ethical orientation. This kind of predatory merchandising is ********, and is now the last straw for my family and I. Checkers, here we come.
