Who called from 3133896451

This number keeps calling me and never leaves a message

Same here. Calls leaves no message.

I just got a call from this number.  It was Jimmy Hoffa from the Teamsters union.  He has been leaving messages on my phone for about a month now reminding everyone in the union that they need to go vote.  He is up for re-election.  A union member must have put down your phone number at some point.

Not sure why I'd be getting this call in Vancouver, Canada but it's really annoying.

Caller ID says "out of area".  Online lookups just say it's from Detroit, Michigan.  We've had no dealings with anyone at this number or with Detroit.
