Rotten Meat sold at Pick n Pay Brigh****er Commons

Today I bought meat from Pick n Pay, after I arrived home I found one pack of lamb braai chops was a different colour from the others, after opening the pack I got a putrid smell. I called the store and complained, the manager says come in and we will refund you which is fair enough. Thinking I could still have a braai with the rest of the meat I said that I would come in the next day, but lo and behold another pack of chops is off. Being really irritated now I called back and complained. The response was that they will investigate and they can't help me now, this is the second time that they have sold me rotten stuff, the first time it was eggs and now the manager says they can't help me. Don't bother to send me one of your automated responses. Pick n Pay should not even sell food stuffs!
