I called the number back and found out it's an automated removal line. If you want your number removed from there database, just press '1' and then put in your #. They should already know the number since everone and their dog has caller id.
I have 4 different numbers same place WCA Clearinghouse. It's getting very annoying. Tried getting off their calling list and they tell you to leave name and address so they can take you off but then it says box is full and hang up. I'm sick of it.
