I got the three calls in a row here!  it was 10:45 PM  and the number called once every minute three times in a row.  I have a voice mail for a reason, if they don't leave a voice mail, the call must not be that important.  Everyone I know, knows this about me... so after the second call/hang-up I knew that it must be some telemarketer.  funny part is I am on the national DO NOT CALL Registry   www.donotcall.gov       I have been on the list for over 6 months.... maybe after a year or so the A-Holes will stop calling.  this three in a row thing with out messages it super annoying.... anyone look into the Better Business Bureau (BBB)?
