McDonald's locations in Columbia, MD

My food Had flies and when I called to speak to the manager she inform me she is the manager but next thing I know she pass me to another person then I ask if she is a manager too but then she transfer me back to her again but wait when I told her my sandwich has flies she just said "OK"....really I had a bad service from them in a first place then flies in my sandwich and all she can say is okay nothing else not even apology. I really don't recommend this place it's sad that all employees arguing in front of customers and management are rude and not able to assist you. They don't need to work in there if they're unhappy of there job be glad you have a job and not be so rude to people specially my husband the man I order that food and my brother in law both in the military they were just amaze how we got treated in person also on the phone as well.
