Who called from 7024485255

I got missed call and my phone automatically call back when I'm asleep.

Has called multiple times in the past few weeks and never leaves a message

I have been receiving random calls everyday from Nevada for several weeks now. They never leave a message.

they are some phony company trying to sell some "extended warranty". they say that they sent some letter to you and this call is last warning before they can take action or something ... if you ask them was that a certified mail they sent .. they will hang up ...
