Overcharging at Pick n Pay Garden's Centre

I have been contacting Pick n Pay Customer Care for over 5 months in regard to the wrong pricing on an item at the Garden's Branch store. I have spoken to Danielle, Chanelle and Imraam who said pricing is an ongoing problem at the store and they can't get it right. I also spoke to Chesnaye, the Manager, who showered me with flowers, chocolates and a refund and promised me the issue would be resolved...but it wasn't. Finally, Karena phoned me, she was employed a month ago to especially sort out the pricing problems in store and she assured me when I next bought the product it would have the correct price. I bought 5l box of Overmeer Blanc de Blanc wine on Friday and was charged an extra R10 at the till. The price showing on the shelves showed R165 rung up at the till as R175. I can't help wondering how many of these items have been sold since I first complained 5 months ago and what that means to the amount of money Pick n Pay is receiving from consumers who do not check their slips diligently. The mind boggles!!!!
