Rock hard chicken fillet

Friday i went to KFC cresta to buy a twister. I have never had to chew that much in my life. The chicken fillet was so hard, RUBBER! Being the loyal customer that i am, i ate and let it slide. Sunday i went to greyston KFC to buy a twister. After bad customer experience i took my twister and came home. AGAIN THE CHICKEN WAS MORE LIKE RUBBER! I couldnt chew the filllet. As much as i love twisters Im done buying them.
