Call that number and they will remove you.

Me too, twice in a row and no messages....

I just got a call from this number, followed what Dani said about calling back to have my number removed :) Thank you for posting that info. I called back, easy to follow automated removal system. WCA Author Clearinghouse is the company.

me too, was called 5 minutes ago

careful.  calling them back just confirms that they have a working number and then the calls really start coming in. if you have a cell phone, just don't respond, or caller id.
