Rotten meat

We normaly buy our croceries and meat products from Pick 'n Pay and this is now the second time around that we found their 'bulk lamb packs', which is suppose to be of best quality, being rotten although the expiry date doesn't state that. We've got 2 children were one is still a baby and I don't even want to think if he has to digest this rotten meat and get sick of it. When we cooked some of the meat and tasted it the taste was revolting! I am very dissapointed in the service qnd quality we recieved and would rather get my goods from somewhere else in the future. We still have meat left over from that and wouldnt even feed it to a dog.
