I called this number back and it said to register my number for do not call list to key my number in . I hung up . Sounds like a scam after reading other post.
I received a call from this number today. I didn't answer, but called it back and it said something about a 'Do not call list.' I just hung up and immediately after received a call from 'unknown.' I am on the National Do Not call list. So annoying.
