Who called from 4072037255

i just got a new phone and they have called me 19 times.

I got also a voice message from this number, its about 1 minute long, but u don't hear anything!!!
-Annoying :-(

It calls me daily usually doesn't say anything except for this time this time it said "Hello Tiffany." and it scared the crap out of me so I hung up.

This number keeps calling me during afternoons mostly. I have no idea who they are. How do I get rid of them?

I've been getting multiple phonecalls per day from this number for the past two weeks, and it's really starting to piss me off.
