beyond terrible service

Friends and i stopped to get a snack, firstly they charged us incorrectly, then we got the wrong order, while ordering, the woman taking our order was speaking to her friends at the back, irritated, we just paid, ate what was given and left but i will never go back there, thats for sure! Terrible service, my first and last! That really upset us all! Kfc's name is being tarnished at the moment, but with service like this? The company is doomed. Staff need to be checked.
