KFC customer care is useless

I sent a complain to KFC customer care after i wasn't happy with the food i purchased , they swiftly rep**** asking for my receipt etc. , so i did that and i received no phone call or email until last night they sent a SMS saying they are closing the case because they cant get hold of me , when did they try to get hold of me and how. KFC customer care is just as *********** as there restaurants.
