Ditto on 3/7/2014.  Time to add another block.  I wonder if some of these hang ups are kids playing with phones?  Not that spammers are innocent - just thinkin....

Calls everyday leaves no message!!!

Rings but leaves no voicemail..

They called at 7:11 PM (1/21/2013), one of the latest telemarketer calls I've had. I didn't pick-up, and they let it ring until the answering machine 'picked-up', when they hung-up.  

Very annoying.  Please stop this.

  call an hang up,  or answered no one on the phone.   call back  number not in service.  no way to identify caller or were there calling from.  shut them down.

Call and hang up. No name or anything to identify the caller.

Call and don't leave voicemail, it's probably a telemarketer.

Hung up after 7 rings!  When will these clowns figure out that if we "the people" don't know who is calling, we "the people" will not answer their harassing calls?

Left no message on the voice mail.  Caller ID just said "Brea CA"

Bogus billing service wanted info about me I wouldn't give them.  when I called back, they had a partitle message which was cut off - maybe recorded from another company.

Call and hang up... looks like the spammers are using a new number.  Same BS, different day.
