Who called from 4803987100

I received a call from this number and it's a Reverse 911 number announcing an Amber alert - a child is missing within a few miles from here.

I recieved a call from 480-398-7100 saying If you believe the world will end press 1 for yes and 2 for no,, at 3am in the morning.

We got a message saying that someone is going to save the world... can't make the name out.

At 12:58 a.m. received an automated system type call that said somebody (can't make out name) was missing.  Sounded like a reverse 911 call.  Tried to call the number back (pissed because we were SLEEPING!) and it just says to enter your employee i.d. #.  Can't find the name of who owns this phone #, but I am going to try tomorrow.

Got a call tonight in Mesa but it disconnected after 3rd ring and there was no message
