Recording offering program to fix our credit - called wife's cell phone and left VM - scam to get info

Didn't leave a message.

Called no VM

Caller ID = "FORT PIERCE FL".  They called twice.  The second call was immediately after the first, specifically 2 seconds later.  My VoIP provider recorded 0 seconds for the first call.  I assume the caller did that to get around my blocking service.  When I answered, a recorded female voice in good English said: "Hi, I'm Heather.  I'm calling for Home Security Specialists..."  That's when I hung up.

I answered because we have a neighbor who lives in that city part of the year.  No one responds to my "hello".
