Rotten chicken marinated

I'm still shocked even now given what I have witnessed last night. I went to Makro in Centurion to go buy some chicken meat. I then decided to by three of those small packs chicken pieces and added a marinated full chicken as a supplement. My Wife even cautioned me when I get home to say why did you buy a marinated chicken? My response to her was that is Makro we are talking about, in my thinking I assumed that the chicken is still in good condition because it was bought from Makro. To my surprise after my Wife cooked the chicken using the Oven, inside the chicken you can clearly see the blue mark on the meat itself and the bones to show that the chicken wasn't fresh. It was clear that the marinate was used to cover the fact that the chicken is not in a good condition. It might have expired or something. I tried testing it, and it was sour and as I'm typing this complains I've a running stomach. It is shocking that a big corporate such as Makro can sell expired food by marinating it in the name of profit, very disgusting! I hope consumers can be warmed of these unhygienic practices. Makro has to be exposed for put Shoppers 's health at risk for selling expired items just for profit
