The person (volunteer?) that showed up at my door seemed 100% genuine. It's possible she didn't know she was part of  the scam.

This is my home phone number.. I work from home and am as honest as can be... I have been reading this and as far as I know, this whole thing seems legit but of course all I do is call people. I will check into this very carefully.
