here's a link to Banctel.com. I just entered my number to be removed from their calling list. I hope it works!
My hubby filled out a form about Quicken Loans to see about refinancing his mortage, now we are getting so many freakin' calls! Quicken Loans called EVERY NIGHT for 4 nights, twice a day, finally hubby was home and answered the call. I block numbers as they come in on my phone as well. It rings once and then my caller ID says CALLER BLOCKED! I LOVE IT!
