Boxer supermarket's meat tastes bad and smells bad after cooking. Unhealthy

My wife and I normally buy at pick n pay, but because of the circumstances this month, I decided we should buy at Boxer store near lister building... The food was okay, however we just opened the worst,, yew we vomited after tasting it, so much waste, this wors does not taste healthy at all, I haven't ate dog meat but that's some animal meat. I regret, no more shopping at boxer. I can't take it back because they will ask for the till slip, however we swiped the grocery and the wors is still in the box.
