Received on my non-published worked number too...no message left...if you call it back it says I am a scammer and give me all of your information sucker...
Been getting calls from this number for over two weeks, daily. Always the same thing, 'Your info was given to us by a friend who has already paid for your service, blah blah blah, energy conservation, blah blah blah'... no options to opt out of any new calls or to speak to a rep. Called the number back and i got the 'I'm a scammer, Give me all your information, Sucker!'
