Very pleasant young man, Devon, tried to sell me energy switch.  Would not give him any info, and he said info is on my utility company bill (OTHER energy companies....ALL with bad reviews also say the same thing that info is on my bill. ) Yeah, but NOT all the companies call only that you can switch).  Did some research and they have three bad reviews, none good that I could find.  Normally would spend more time checking it out.  He was prepared for EVERY question I threw at him, so they are sounding more legit.  Also the name he gave was Sperian, although the call came from PA (he said I could call back for legitimacy),   It is tough NOT to answer when you know the call is within short traveling distance from your home and could be a family member.  If it had shown it was from out of state, I would not have answered.  In the background, there were lots of voices speaking, so I am listing it as telemarket.
