Old burger and not getting the order right

I ordered two happy meals with nothing on the cheese burger. Just the bun and patty. 2nd order was a chicken ranch burger. When I got home we realized that the happy meal burgers had all the toppings on when I specifically asked for non. The ranch burger was not a ranch burger. They got the order wrong. But to top it all the bun and chicken breast was old. It seems this burger was made in the morning and just past on to me. I was so disgusted I could not eat it. I am very disappointed. I promised not to buy there again.
