Not satisfied with quality of chicken

I went to Chicken Licken Roodekop to buy their 15 pieces which cost R204. 00. Got home their chicken is Black in colour and has a very bad smell which clearly tells me that they don't change their oil not even sure that chicken was fresh. None of us could finish their meat even kids. Until now some of the meat is still in the fridge and normally we don't have left overs. I am a catering manager by profession for 28 years so food is my language. This is disgusting and not acceptable a waste of money in these difficult times.
