Pnp expired stock sold as fresh stock

Good day. I am writing this because of no response. And to notify other people to look at dates on products before buying any fresh produce items. On 23 November I went to pick n pay at kemgate, kempton park, I believe they also call it valley pnp. I bought a bag of 7 kg PNP potatoes, when I got home my wife started using the product. She noticed that the potatoes quality was terrific. I then check the bag for a expiration date, I found it and was labelled 30 October. I contacted customer care on the email address on the bag. I got a response, but could see it was a auto mated reply. I took photo's of my slip and the bags sell by date. I threw out the sunflower oil and potatoes. Because I don't want rotten spoiled items in my house. So I left it in the hopes someone would contact me on Monday atleast. It is know Monday at 15:30 and one has attempted to contact me. So I am guessing it is common policy to sell almost a month old expired stock, supposedly fresh produce to customer's as fresh stock. I do hope this finds it way to the revealant people so this matter can be addressed.
