Who called from 3187411183

Hang ups all hours!!!!!!!

Called at 4:35 am  missed the called and so I called back and it said no longer in service

It has called me 3 times in the last 3 minutes & only get a sound like a "beep"  "beep"  "beep" & no one answers.  Called it back & got message it is disconnected or no longer in service

called asking all kinds of info and wouldn't give it to them.

Someone from this number called one of my employees and made threats towards her. We called the police and they sounded as though they knew who it was, but wouldn't tell me who it was. I bet they don't do a damn thing about it.
