We are on the DNC list and this number calls day and night and does not leave messages. WHen I answer the phone I do not hear anything. This is pure HARASSMENT and want this to stop immediately!

Another uninvited caller.  Called twice in 2 days.
From comments here, I'm happy we did not answer.  Is there any protection from these?
Do-Not-Call List is another example of useless government bureaucracy.   Note, I said useless.

The DNC list applies only to legitimate, participating telemarketers. Telecriminals (like these), do not follow it or any other laws.
