The only ones that honor the DNCR are legitimate businesses. Unfortunately many of these telemaggoters are based in countries that will not cooperate with our investigations.
When it comes right down to it, I make it a practice to try and ignore 99% of unfamiliar callers.
I called the number back, and after the whole prompt plays, it gives you the option to select #2, to be added to their do not call list. Hope this helps. I friggin hate robo calls.
This was on the news last night (February 25) DO NOT HIT #2 - this sells your information as a "good" number to other companies and you get even more calls!!!!!!!!!!!!!!!
