Calls me daily, sometimes twice per day, for the past three months. My Caller ID says "Habitat for Humanity". I don't answer, although several times I have picked up the phone and given it to my 18-month old son and let him garble into it. I suspect it is from a company that is paid by Habitat for Humanity to solicit contributions. I've heard good things about HFH and don't think they would have the audacity to continue calling incessantly like this.
