Told me I won a trip.  I didn't enter any contest for this.

Guy with a strong Indian accent calling from an obvious call center saying he's from Windows and he needs remote access to my computer to clear up a virus.   And he knew my first name, so it wasn't completely random.  Weird.  Anyway, obvious scam, spoofed number.

Stop the calls... this is my sons phone and we know no one in california

Don't answer in any way or consider a call blocker to stop them. Giving them no kind of answer gets to them after a while. Have to be patient and let the phone ring.

I've tried calling the number back but it says that is has been changed or disconnected.
