KFC review: my order was incorrect, waited for 30minutes and poor customer service among the employees and very unprofessional

On January 2, 2019 I placed in order at KFC around 9:40 p.m. When the cashier came to the speaker, all I could was loud music and loud talking. The cashier ask me to repeat my order several times. I pulled up and paid for my order, which was $17. 49. The cashier gave me my change and the receipt . I looked at my receipt and the order was wrong. I told the cashier and she told me that she knew what I ordered. As I was talking to her several other employees came up to the window and they were horse playing and laughing as I was talking. The cashier ask me to pull up and they will bring my order out. At this time I was the only car in line. Ten minutes had passed by and an employee came up to my car window and asked me what was my order again. I gave him the receipt. At this time it was about 9:55 and I went inside the building. One of the employees told me that they were closed. I told them that I had been waiting on my order for a while. The guy told me that they were about to fix it up then. I became very upset because I had waited all this time and still no order and there were only two cars that had been in the line since I had placed my order. They gave me my order and I asked for the receipt back and they stated that they didn't know where it was. I drove home very upset. I made it home and took my food out of the bag and my food was cold and was order was in correct.
