Well, your callers are criminals, and have no regard for the Do Not Call List.  The DNC works perfectly well for legitimate telemarketers.

did not recognize, did not answer,  they left no message.

This one just called here, too, though he's in no danger of finding anyone here answering calls from strangers.  Thanks to all of you who've had contact with the caller, yet another attempt to compromise my healthy back.  I can block this one right now!
