Keep calling and they said " I have a call waiting for you"  Just like a long distance call in the old times. The operator after refusing to ID his company. Say I will now transfer you to the call. Another person began asking for a "Ferando Something"  He refused to leave or give any more data and said I call some other time and hanged. I believe this is scam. People are now trying to sell, blame, or get you in trouble.  I will have them blocked from my phone!
