Burnt chicken

We ordered fast food when our car went in for a service. As we live in a rural area, we do not have this luxury often. On our way home, we opened the brown KFC paper bag and started consuming our food. Mine was delicious as ever. My husband discovered that his chicken pieces had been burnt so badly that he could not eat them. We were already too far from the store and were therefore unable to return to complain. On the same date I sent KFC's customer care an e-mail with pictures of the burnt pieces attached. This is not the first time that this KFC have given us service or products to complain about. I received an e-mail that notified me that they had received my complaint. From 27 November to date I have not had so much as a call from them to acknowledge.
