This person has called me several times a day for days now. It's always while I'm at work so I have only picked up once and it was something about a settlement. Now I just let it ring. If you try to call it back it is always busy.
United States Medical Department? If they managed call me with that name, I might bust out laughing and say, "Really? Well I work for the Department of Federal Investigations. Maybe we know each other. Did you attend the summer picnic in Nome Alaska?"
