Multiple phone call someone in my family

Caller with heavy middle eastern accent stated the first call (2/17/2016) his name was tim miller. Second caller (2/18/2016) stated his last name was also Miller. Stated they were calling for some medical/ health board. First caller didn't ever say my name and second just asked for me by my first name. Second caller repeatedly told me to shut up and called me a stupid B**** when I questioned their "company" and said I believed they were a scam and would report them.
