MR D FOOD ORDER

I am beyond disappointed with McDonald's Auckland Park for the food they delivered to me. I hope my concern land in the hands of the right people. I payed R90 for my food, only for them to deliver fries that looks were half empty. The fries were cold, it looks like the order was meant for someone else who failed to collect it or something. I ordered watermelon mcfizz, they delivered orange or mango flavored mcfizz, i am not sure of the flavor but it was not watermelon. Why wasn't i told that they ran out of it so that i can choose a different drink? It's always like that. Is McDonald's covering their costs at the expense of my order and satisfaction or what? Hence I'm thinking this order wasn't mine and it doesn't worth the money i paid. I'm so disappointed at their service. You've ruined my night after the long day i had. It might be my last time ordering food online. It looks like they take advantage.
