Just used your link Chad to stop unwanted SPAM phone calls from Soveriegn Bank of PA. They keep calling with a # on the called ID that is a non returnable #
So I used the link to find their main # and complain about the unwanted calls.
Jeez! I have an unlisted #. How do these companies get it? It should be illegal to sell a unlisted #. I know many companies share and sell private info. Make sure you read all the "opt out" papers that come with your credit card and other bills. That keeps you off of certain lists. They try to get you to stay on by offering deals and discounts, but its just to be able to market items and watch what you purchase.
Be VERY careful of whom you let have your info....
