Old Rolls from Kfc

On Saturday night we went to KFC Protea North to buy 4 chicken lunch boxes. when we got home we could not eat the burgers because we were given old rolls that were warmed and sold to us. we had to throw the rolls away. I am very disappointed at their service if something is old why not dispose it .I am not a fan of KFC we went there since it is closer to our house but after this experience i doubt that we will ever go back again.
