When I call back, the recorded message didn't give name of company but said it was "an urgent public service message regarding my electricity bill."

Typical robo-dial/SCAMMER call pattern - land line rings, caller ID shows "Cleanplanetpro" and "112015481054", do not recognize, do not answer, rolls over to voice mail, no message left = SCAMMER = BLOCKED ! ! !.

There are numerous reports on other sites showing complaints about "Clean Planer Pro" being robo-call and scam, using several different numbers, but not this specific number.

Same - BLOCKED.

Did not answer and no voicemail left

Call my cell, no message, robo call
