This number calls me, but doesn't leave a message

just got a call just now..

It is Sprint

Called me three times in about 4 hours.  On my voice mail, "To continue in English, press 1.  (rest of message in Spanish)".

Dialed it from a separate number.  Recorded messages says, "This number is not currently in service", but doesn't hang up.

This is the sprint customer staisfaction survey hotline.  It will keep calling you until you answer and spend 2 minutes of your time answering questions that really don't matter.
