Who called from 4075198967

THey called, I answered, they gave only silence.   Waste of time.

THey keep calling multiple time per day.  They never leave a message nor is there anyone on the line if I pick up receiver.  WHAT IS THIS?  Harassment via phone.

There should be laws.  THEN ENFORCED!

Caller ID says  FLORIDA

called at dinnertime and no one on line--we are on no call registry but still get unwanted calls

Have called twice in 2 days.  Ignored the first call.  Answered the 2nd call.  Absolute silence.  Told them to Bugger Off.  Caller ID reads: FLORIDA.  Blocked the calls.

keep calling, 5 times so far on 4/18/13
