KFC zinger wings

I went to KFC in the umhlanga Cresent on my lunch break at work since we work on meridian drive so it was easier to go to that branch. I ordered the zinger wings and my usual burger and mash and gravy. Everything was fine but when I took a bite of the zinger wings it tasted a bit off. So I checked it and the skin was dark in certain areas, one of them had a glimpse of white mold. After my friend and I ate it, we felt nauseas and had to throw up. It was the worst experience especially since it's at work, I order from them all the time and today was such a disappointment
