Got this call today from someone claiming to be calling from Pontiac. I asked if she meant General Motors, she clarified saying she was calling from Pontiac. After I explained that Pontiac has been defunct since 2010, she hung up.
Got a call about my car warranty. They knew my full name make and model/year. They transferred me to different departments and everything seemed to be as a normal company would be. When I called the number back it said "this number is not in service".
