this has only happened once, but it was weird. A recorded guy's voice half laughing saying..."whoah!!!! you've been spy called...or dialed or something. I was driving a truck and had fans blowing. I have no idea what that means, since I don't go around calling folks I don't know, and I have a flip phone, so go figure. Should I be worried? Is it something that if you answer, they somehow get your info?
