Expired meat

I bought 3 packs of pork chops at pick n pay Flora centre, I put it in the freezer when I got home, the next day we had people over for supper and to my surprise all three packs of pork chops were off. It is sad that they keep food like this in their freezer. I have called twice to the store to report it but keep getting put on hold. It is unacceptable and not okay as had we eaten the chops we would’ve all suffered food poisoning. Pick n pay needs to check their stock before selling
