If it is a solar company, they aren't very BRIGHT! Why would they use a number, when called back, results in a carrier message that the number is not in service? Obviously there is some nare do well out there trying to rip off the public in one or more ways! Where the ¥£€# is law enforcement that our taxes are supposedly being used to protect us?
I didnt answer (I never answer any numbers I don't recognize). They left a message which was cut off at the beginning but basically it said "free electricity, save on electric costs, extend the life of your roof, and save the environment." Then goes on to say "Please press 2 to be placed on the Do Not Call List". I wouldn't press that button if I got paid to!
