They called, I didn't answer, they left no voicemail.

Called and left no message

Called and left partial message on answer machine.  Some kind of home improvement scam.
We haven't answered out of area or unknown telephone calls in over a year.  Have now blocked the the 661 area code.

No more calls from these fools.  Check Amazon for blockers - they work and they are inexpensive.

CALLED AGAIN - BLOCKED FOREVER.
Our phones do NOT ring when a blocked number or a blocked area code comes in.

Blocked BEFORE they robodialed our number.
