I revoiwed this page and went to cars.com. I was getting emails and phone calls. They sell their information to 3rd parties (ALOT) and those companies can be opted out of sending you any further information.  Below is the link. I am continuing to see if there is a way to opt out of calls and will post any further findings after my research.

Good luck

This is CARS.com...call them back and tell them to stop calling you...I called the phone company which with the are associated and they were NO HELP AT ALL! DO NOT GIVE THEM YOUR NAME AND ADDRESS

who is this - they have called me four times today....im about to go crazy!

Just got a call from +3212600121. What does the plus mean? When I answered, they asked for my name and when I ask yes, it was me, where are you calling from, they hung up. Phones have become such a nuisance because of this kind of crap.

They've called me three times over the last several days.  No one says anything when I answer, and they do not leave messages.

I am receiving calls from this number daily, sometimes several times. This caller never leave a message when I don't answer, and when I do, there is silence on the other end. Who is the owner of this line, and what do they want?

This mother f****rs call my house every day! They have no balls and do not leave a message!  It only shows name unavailable and the same f****ng number 321-260-0121.Stop harrassing me moth******ers!
