When I received the call from this number, I could not answer.  No message, so I called back.  It states that the phone # is disconnected.  Now how can that be?

A number unknown to you called. They left no message. There are many cons and scams going on these days. WHY did you call back a number you don't know?

I received a call from this number; so, I answer and Its automated  telling me to please hold. So, I hang up and call back. The number is then stated as disconnected. Go figure.
