Scam call from "Cindy" from "Sustainable Energy". Has called several times on both land line and cell phone

Call rolled over to voice mail.  Computer  noise and voices in the background  with one asking 'what is your address? '

Caller ID San Jose CA called 6:57 p.m. no message left-->blocked

This afternoon, I got a call too. Probably a swindler trying to get me to empty my bank account into his. Not falling for it. They did not leave a message. If they don't leave a message during the first call, I block them forever. If the caller is legit, they know how to reach me by snail-mail.

Called me when I was in a meeting. No voicemail left. Blocking it b/c a number that I don't know, and not any business that I'm expecting a call from.
