I called all three and they start with an automated message saying "please press any button to be removed from automated call list"  so I did and it said it would take 24 -48 hours to remove me.  we'll see....     I still dont know who they are.

I called back and it gives me the number is incorrect. Probably a spoof number for telemarketing

They didn't leave a message.  When I attempted to return the call, I got a recording that it was not a working number. I live in 310, and I don't often get SPAM calls from local area codes.  My guess is that it's a technique of appearing to call from locally to make us more likely to pick up.

I got a call from thsi number too; this morning. I didn't answer.

Block the number... End of story
