Who called from 9252579075

No caller ID.  I didn’t answer, and the caller did not go through the prompts to bypass my call screening device.

Called and left no message.
Very similar number called a little later and left no message.
I was not able to answer to find out what the scam is.

Same happened just now. Call is from Orinda, CA with no message.

"Free Home Security" scam.
Finally connected with their automated response voice - the fifth time they called my house.
"Jane Wilson with Alliance Home Safety Center" informed my that I have been selected to receive a free wireless home security system as part of an advertising effort.  (A common and obvious lie used by lead hunting scammers.)
This is an automated voice looking for positive responses.  When I kept asking questions, it would loop back to its original pitch , which is kind of fun for a while.
I eventually asked too many questions and it hung up.
Of course, there is no 'Alliance Home Safety Center' to be found - they are just law-breaking lead-hunting pests.
Fake name, fake phone number, fake offer.
Scum.

Same as above.  Alliance Home Security wants to give me a free home security system.
They have called here 7 times now.  I have asked them twice to remove me from their call list - but the automated response system hangs up when you do that.
