Note - next time he calls, I will pretend to be a home owner, interested in the solar panels, play along, get the name of the company he's representing, then report company info to FCC and my County District Attorney's Office.
Same guy, with an Indian accent, has called me from two different numbers. Phone numbers obviously being spoofed. He's asking if I am a home owner and want to buy solar panels. First time, told him not a home owner, and firmly asked to have my phone number removed from data base. Same guy called next day under different number selling same thing. This time called him out for spoofing number scam, threatened FCC, he hung up on me.
