Wrotten meat and bad customer service

I usually do my grocery shopping at Pick n Pay blue hills and sandridge square and I'm disgusted by the fact that they care about making money more than our health as customers. Not once but 3 times I bought their chicken in trays and found worms in it as I rinse the meat with water before cooking. The lamb trays they sell are wrotten and have a foul smell. When will stores learn to get rid of anything wrotten instead of changing dates on packages to make it look like it's fresh food that they're selling. For an upmarket store this is disgusting and the worst customer service at sandridge square where when you ask why there's people packing for other customers and I have to pack for myself and to get a response from the teller that they are not paid enough to pack for us I have to do it myself is just something else. I will never recommend any of these stores to anyone
