I doubt that Sonoma Court is offering home improvement services.

Some thieves called me 2X, somehow thinking that I'm old, a home owner, and likely to be addled enough to invite them over for a shoddy, overpriced, unlicensed job and a distraction burglary, but only some of those victimhood criteria currently apply to me...

Received call 11.36 am 7/23/14 from a person(?) who said that his name was ruben and that he was with an energy co. As soon as I could get a word in edgewise I let him know that I recorded all sales calls and that we were on the do not call list. He the let me know that the do not call list meant that they could not see it. He also became quite loud and vocal when I told him not to call again and to take us off of his listing.
I did manage to trace the number to a land line in Santa Ana by using  online "People Smart."

Like others, I received a call from 714-368-0968, caller ID showed "Sonoma Court RE". I didn't answer it.

I notice that the calls reported from this number are coming in on July 22nd and July 23rd, 2014, so I guess it's a new number the fraudsters are using for a few days.

Called 5:16 PM.  Caller ID showed Sonoma Court RE. Spokeo lists calling area as Costa Mesa which is in Orange County not in Sonoma County. Dead air when answering machne picked up.
