Answered, convincing robot asked "if anne was there". When I asked to repeat, they asked the same question with the same inflection. Said No and they said there is no message and will call back later then hung up.

got to calls back to back from these people.  I hate some spam on my cell phone.

Clearly a scam! Asked "is Albert there?" I'm not Albert, nor do I know an Albert.

Answered the call and it automatically hung up.  Seems like a robot calling to verify active phone numbers.
