Worst KFC Service at Meyersdal

I have had the worst experience ever. I ordered 2 colonel burgers and 2 colonel fully loaded box meals with buddy cokes. I end up getting only 1 wicked box meal. And 3 colonel burgers. I went back to give back the burger and was asked to pay in additional money for the box meal. I didn't have my card so asked them to give me back the burger so i can leave because i have been waiting for 20 minutes but they couldn't even find the burger.
