Who called from 4042487994

Pone rings after 11:30 PM and when I pick it up, I only get a beep.  I've tried calling it back, but I only get a busy tone.

Called @ 4:00am, waking our entire family from a dead sleep!

phone rang at 3:24 am, but there's no response when you answer.  very annoying.

got 7 calls the same as yours and never once do they answer

The very same thing called at 6:00am - just a beep. Is there not ANY thing someone can do? Very annoying and scary when your phone rings at strange hours, makes you think something is wrong with one of your family members
