We NEVER answer unknown telephone calls!
New week - new scam/criminal caller.  Recorded message about energy savings.  No company name and no phone number was stated.
Immediately blocked the number.
Folks, you have had an answering machine for years.  Now is the time to consider the purchase of a call blocking phone or a call blocking device that can also block entire area codes.  We have and use both - they are inexpensive and they work

BS telemarketer call. Actually left a voicemail.

CID: Huntington Park, CA
Got a call on my cell, left a message about "replacing roofs, energy saving projects in your home, for a free estimate press 1... "
That's dumb... You can't press 1 to a voice message!

10:01 am today. Either no message or my robo call blocking service got it.  Wish I knew which.
