I did. The problem is, as I understand it, "Robocalling" is illegal altogether. So anyone doing this type activity is not going to be following the rules. They're scammers, out to steal from those unfortunate enough to fall for their games. I've told them not to call, "Pressed #1 to be removed from the calling list", asked for deviant sexual favors, threatened them with bodily harm, etc, etc.... Nothing works.
So now I'm pretty much down to wishing someone would hunt them down, shoot them and burn their businesses to the ground.. Too bad that's also against the law.
