KFC review: fill up box

I originally asked for breast and wing meal but was told they were out of xtracrispy so I ordered the fill up box. When I got home the chicken was not cooked enough the breading was falling off and it was slimy. The order was supposed to come with a cookie which I did not get. I was extremely unhappy with the food . I've never had a bad experience in 25 years with kfc till now.
