McDonald’s complaint: Incorrect order

I made an order through the drive through and when I approached the payment window an employee had their back to me and was chatting to a friend, I actually had to say can I pay please ? When I get my order low and behold it’s incorrect… I tried to resolve this by calling the resteraunt and when I said what happened I was told the girl who was working the payment window had to deal with 2 payment windows which I get but she didn’t seem too busy to be chatting away with her friend and when I mentioned this a girl named ivonne who said she was the manager starts saying she dosnt appreciate the way I was talking … I didn’t swear I didn’t call anyone name’s I was simply trying to get my point across about maybe the girl at the payment window should have been doing their job rather than chatting to friends … I have never been spoken to like that off any company before. I requested a call back from a manager which I doubt I will get but I will be calling back if I dont
