KFC Kabega Park Sell Blue Old Chicken?

bought chicken from KFC in Kabega Park PE in December... However when we ate the chicken it was blue. we ended up throwing most the chicken away and mind you we bought a 21pc and a 6pc sharing. all our money down the drain ans kfc is expensive!! We are still waiting For Julie From.Customer Servies to get back to us but as to date mo communication was made! Pathetic Service just like the pathetic blue chicken they sell!!!!? definitely not buying KFC again!!!!!!!
