Very garbled message about 1 minute long left at 1:25 PM Mountain Standard Time on November 10, 2015 on the answering machine at my number 780-438-1103.  The beginning of the message is unintelligible.  At the end the message clearly threatens that if the above 819 number is not called, an arrest warrant will be issued and my bank account will be frozen. This call is not based on any relationship to me.  It is not really a "prank" because of the serious nature of the threats.  It must be a malicious scam of some kind.
