Expired/OLD/ROTTEN Meat

On Sunday 18 Feb 2018 we bought lamb chops from Checkers Elridge Corner, when we got home, we noticed that the meat was actually rotten, it was the worst smell ever and it has a slime layer on top of the meat. We took it back and Checkers kindly refunded us as well as replaced the meat with a "fresh" pack, as per the manager at the store, the meat we orignally bought was old meat and was not taken off the shelve. We took the new meat home and it was in the fridge the whole time. I was about to cook the meat when I noticed that it had the exact same smell/look as the previous packet which Checkers replace and refunded. I threw the meat away, cause I will not even give it to my dogs. This is not the 1st time we have bought rotten meat from this store, I will not buy meat again from Checkers Elridge.
