Blue and brown chicken PNP walker drive

So today I went into my nearest Pick n Pay store( Walker Drive Port Elizabeth). I purchased a marinated peri peri chicken tray. I grilled in the oven and was ready to have lunch, only to discover that the chicken is blue and and dark brown on the inside! I'm so disgusted! I actually took pictures. Pick n Pay your standards have gone down the drain. Will not return to the store again and would rather shop at another store.
