This number has called our home seversl times a day despite being told thst we are not interested in the service offered.  The are from Sperian.  A woman has came to our door and aggressively asked for our electric bill several times after being asked not to return.  Even if they are offering a savings, the disturbing way these reps have behaved has turned me off to this company.   Next time the woman shows up I will call the police.   The next harassing call will be informed of that as well.
