McDonald’s complaint: Almost whole order wrong

My husband when to get food for supper for 4 people. When he got home the only thing in the bag that was right was a medium fry. Plain CB with just mayo had ketchup on it, Double Qtd pound with just ketchup was loaded with onions and pickles, another Double Qtd pound with no ketchup or pickles had those items on it. One cinnamon roll unheated was heated. I carried it back and waited about minutes for the whole order to be replaced. Other customers in there complaining about the same thing that goes on all the time at this location. Got my order and went to my car and checked the order and it still had one Qtd Pounder wrong. Had to carry it back and wait about another 15-20 minutes. Finally got it right after hearing the manager say the F word. She was very polite and offered me a pie for my wait but, I declined. My husband goes here every morning and at least a couple times a week for takeout. Get home with the food and about half the time the order is wrong. Something needs to be done about this location before it is to late.
