Got a call from them today, 2/16.  I re-upped my listing on the do-not-call a couple of months ago, discovering then I had also previously registered in May 2014.  It apparently does no good, as I receive a call of this type from various parts of the country at least once or twice a day.  My phone service doesn't feature call blocking but I love my caller ID.  I try to be obnoxious by answering and then just hanging up.  Of course, it does no good but gives me the illusion of being obnoxious.  I'll see about what one poster suggested - reporting to do-not-call registry.

This is something you'll have to do.

We have received calls from this number several time the past week. I dialed the number and received a busy signal several times, I finally got through to someone.who identified herself as Alex and she was calling for Energy Experts.....obviously a call center given the background noise of other conversations.They are selling energy conservation products to home owners. According to North Carolina Yellow Pages, this number is a land line located in Charlotte, North Carolina. The listing has a warning that this is probably spam and the number should be blocked.

Another "solar energy" telemarketer. Block the number.

I keep getting phone calls from this [***]. What do they want? Can we all report them ?
