Missing food DFD***

I purchased food from McDonald’s the order was as follows:

4 Big Mac burgers and 2 large Mc Flavour fries. My order arrived and I have one large Mc Flavour fries missing!

The mr delivery s****** came to drop off my food, the bag was completely sealed and wasn’t tampered with. McDonald’s you need to make sure your staff stops talking to one another and pay attention to what they doing. This is not the first time i experience ****ty service from you people.
