I received a call but my phone didnt ring, just got the vibrate that I missed a call - no reason for it, my ringer was not turned off.  Then a few seconds later this number calls back and when I answer they don't say anything then hang up.  So I called the number back and get a recording that says, "I'm sorry but our office is currently closed", gives the office hours and says its Pacific Time.  I'm in Eastern time zone and have no idea what this number is so I Google it.  Similar sites to this say the same, calls, hangs up, and return call gets a pacific time message stating office is closed.  BUT, other results show this number as a Beltsville or Riverdale, MD number...confused
