Disgusting meat sold by shoprite

I've always had bad experiences when buying meat or meat products from this store but yesterday topped them all. My wife is pregnant and she has big cravings for braai meat and yesterday was one of those days she was craving braai chicken so i decided to go to Shoprite in Jabulani Mall (soweto) where i bought 1 tray of already Marinated chicken and pork, went home to spoil my wife and kid with a delicious Sunday night braai only to find that i had wasted R150 on rotten meat. The chicken is very pink and very dry and hard you'd swear it's a biltong and the smell was horrible i took 2 bits of both and couldn't go to work today coz i have a running tummy. Luckily my wife and child didn't even attempt to taste otherwise we would be having the whole family sick today. This is very bad for a shop as big as Shoprite and very big risk for our health as the consumers of their products.
