KFC bad service

I was at naboomspruit KFC. The cashier name was Jane L. I have order 2 chicken lunch box and two small coke. Before we order I have ask her if it will take long to prepare she didn't reply me she was talking to her friend guess what she gave me a wrong order it was streetwise 3I saw that in the bus that it was a wrong order. She didn't listen to me that why she gave me wrong order. Even the slip is written 2 Chicken lunchbox. I'm so disappointed. I didn't even et it.
