KFC

We ordered our dinner through drive through. We ordered several items and all original chicken. We was told it would be about 8 minutes for the original. We agreed to this and pulled around to the front. After waiting 20 minutes, my husband went in to get our food. He was in there an additional 10 minutes to retrieve it. The order was wrong. We got a mix of the chicken original/crispy. I do not eat the crispy! My son's food was missing as well as my extra gravy. We also was not given a receipt for our order! My husband didn't get an apology just frustration for the employees of being overwhelmed due to messed up orders. I don't ever complain over mistakes but people aren't getting item they pay for nor even an apology. Please fix this! Thank you!
