I get 3-5 calls per week from this number "Clean Planet" lower my power bill. I think it's either SPAM or a solicitation call. I don't have a Smart phone so can't block, but sure wish this would STOP! I am "clean" enough!
Caller ID displays Clean Planet PR. Answered but on mute. Nobody there, it hung up. Called the number back and it was an automated system giving me options to talk to a rep or have my number removed from their call list. No information at all in the message to who or what they do/want.
...because 980 is a Charlotte area code I decided to try a little cross checking to see what I could find:

and even though the article references a 704 area code(also Charlotte) I have discovered a lot of cellphones are '980' numbers
