YES... I.e.: if you are on the national DNC registry, and an automated telemarketer keeps calling you, the best thing to do is have the state att'y general mail them a letter, and eventually this will actually scare them enough to stop calling.
I keep getting this call every few weeks from this number. I pressed one to speak to someone and complain but no answer and I think I just screwed myself because now they know i'm a live person.
603-464-5770 is another scam about car warranty crap. beware!
