I am a Bostonian who was just called by this "Waltham" number. I was reading your comments on it even before the phone stopped ringing. Thank you for the information. I NEVER pick-up the phone unless I know the caller ID.
Fast talking female recorded voice talking about "the important notice you received regarding your electric bill". Go away, telemarketer. Also, when I hung up it did not drop the line right away so they are breaking the law there too.
