Just got a call from this outfit.  They are a "solar" company robo-calling people and ignoring the Do Not Call List.  If you don't answer, they will not leave a message.  Since they are local to me, I called them back to find out who they are.

They just called.  They let the phone ring twice and they hung up.  Blocking

Called today.  I didn't answer and they didn't leave a message.  From what I have Googled about the number, it is now blocked.

6.24 I live in Mesa and received 2 calls today from 480 281 1000.  They both rang through, no message so I Googled the number and found this site.  Since another respondent had phoned them, I did, too.  Female with oriental accent answered with "Mr Smith?" -- her caller ID had given her a wrong name, but she proceed to tell me about real estate deals involving the equity in my home.  I told I was reporting her the Do Not Call authorities and I did at https://complaints.donotcall.gov/complaint/complaintcheck.aspx

stop calling me every day.
