Real bad customer service Uber Eats and McDonald's

Tonight I had an experience with Uber Eats had a order two items ice-cream and nuggets where not with the order. The delivery driver told me that I had to go the macdonalds. So I when to the macdonalds can you imagine. The lady manager at the wanted to help. But when I got home my meal was changed to a small nazo double meal small from a mcmegameal🤦♂️. How do you pay for one thing and get another and still drive up and down from a delivery service. Suppose to be convenient
