That's what everyone has to do. Call your senators and congress people. Let them know you are sick and tired of getting these scam calls and calls in violation of the DNC list. BTW, trying to file a complaint with donotcall.gov is a worthless waste of time.
I got a call from this number on Sunday, Jan. 8th, 2012. The tag line on my callere I.D. read "Electric Bill." I don't answer calls from numbers I don't know.
I also received one with the caller ID showing electric bill. I live in an apartment, so I would never have an electric bill any way. Not that I would have answered anyway.
