An older-sounding woman called my dad's cell phone from this number and left a voice mail message saying they were "Grandma Ruth." They said that they were trying to get a hold of my wife (they knew her first name) and that they had gotten the number from me (they knew my first name). None of us know anyone by that name nor anyone from that part of the country, and I've never given my dad's number to anyone. I would chalk it up to a simple wrong number, except that the combination of our first names and my dad's cell number seem like too much of a coincidence. Maybe a scam?
