Called my house today.  1 second blank message.

Caller ID says "Needham   MA".  They leave no message.  Interesting that this name is associated with Lynn, Malden, or Medford, but not Needham.

I call back (using *67 to block my number).  I hear the following, "You have reached a number that has been disconnected or is no longer in service.  Please, check the number and try your call again. P-U-A-B-O-1-4"

So a spoofed caller ID and the inability to be called back.  Smells like a SCAM.

this guy called early this morning, he didn't even have our name right.  I told him he had the wrong number and hung up.

Called this AM, offering $60 chimney cleaning from the original price of $150. When I let him know I'm not the owner he was thrown off the script, said here's my number for your landord to call me. When I said it's on my caller ID, he said oh that's a computer phone not mine, and rattled off an 800 service. Called himself "Vinny"

Called today. I did not pick up, they did not leave a message. Going to block this number.
