Poor Service/Packaging

I went to McDonalds to purchase a Tenders snack box as i was about to pay they informed me that the sweet and sour sauce is discontinued i then took an alternative sauce, I payed for my order and proceeded to the next window for collection, when i received my order all my chicken nuggets and chicken tenders were just thrown into a happy meal box and i was told that it is the new packaging, the box was so full it could hardly hold the chicken in and it fell out. i laid a complaint and all they could do was say sorry with no further feedback
