Solar Sales .....telemarketer

Didn't pick up.  They didn't leave a message, either.

I just received a call from this number on my home phone. I called the number from my cell and a girl/woman answered saying "Thank you for calling Zero Down Solar". I'm on the National do not call list and this is exactly why. What do you have to do in order to get these companies to comply?

Has called several times and does not leave a message.
