Who called from 8477692362

called my phone but won't pick up.

called me but will not answer my return call.

Caller advised he was calling about energy but did not want to bother me if I was waiting on another call, they would call back at a later time.  Asked what the emergency was or what the issue was and they repeated they would call back at another time.  I dont want the call.  It is suspiscious..almost as if they call to see if you are home.
