Mislabeled food items

Extremely disappointed with Woolworths. I purchased the Easy to Cook slow cooked lamb shank for R220. Once I began preparation I noticed that the gravy contained beef. I was really taken a back as I do not eat beef. This is unnacceptable and should be disclosed explicity on the front of the packaging. This is my second such experience - Woollies game biltong is flavoured with beef fat. I am very hesitant to purchase any product from Woollies as it appears that they opt for the cheapest source of flavour. I am usually a loyal customer and huge proponent for Woollies good. <br> <br> Game should be game, and lamb dishes should use lamb stock. Isn't that obvious?
