BAD CHICKEN FROM KFC......

On the 3rd of July 2018 We had a power outage so i decided to stop off at KFC Mulbarton South of Johannesburg, to buy food as it was convenient at the time and my 3year old Son enjoys their Mash, I bought him a street wise 1, my wife a twister meal and i took the street wise 3........ My wife had her twister meal to a point when i realised my chicken had a bad taste and was an off colour......between a darkish brown with a slimy texture..... it was dark and we were eating by candle light so after about 4 bites as i came closer to the bone i smelt a bad smell and decided to throw it away..... i took the chicken away from my son and only let him eat the mash with hes roll.....My wife smelt the chicken and said it smells off........i was upset as iv'e experienced a similar experience at Kfc where the chicken wasn't cooked properly with water still dripping out when taking bites.......i would like this matter taken further as i had to take a day off work from this.... I experienced bad stomach cramps early hours the next morning vomiting from there on........ Please guys its negative feedback like this that make people think twice from buying food from KFC!
