Expired and False Labelled Meat Products

Hi<br> <br> I purchased meat products from Pick n Pay Observatory on 24th October 2015. The meat products bought were labelled with a green sticker saying Lamb (Wors, Chops, Sausages). When I looked at them, at the time of cooking, I noticed the price tag states 'Lamb & Beef' which is miscommunication. Furthermore, I decided to cook the Wors on the 29th October 2015 (it was kept in the freezer from the day of purchase). While cooking the wors, I notice it was old, rotten and sour. Please advise and contact me urgently regarding the above. As I had high respect for Pick n Pay but now am very disappointed. I still have to other packs of meat purchased but am afraid to cook them and am will to send a photo of the labels that differ. Your feedback will be greatly appreciated. [Email Removed] ***
