I have been getting calls for 3 weeks now from this number and 202-607-2749. The callers all have foreign accents and are looking for people who don't live here. I have had this number for over a year. I have repeatedly told them the people they are calling for don't live here. When I don't answer, they don't leave messages. I called them back yesterday and was told my number would be removed from thier list. I was fed up today and demanded (politely) to speak to a supervisor. I was told at first he wasn't available. After several times of this I said I wanted someone in charge on the line or I was getting a lawyer and filing a suit in US Superior Court. I got hung up on, and when I tried to call back, was immediatly kicked to a voicemail system.
