I received three calls yesterday from this number, no one on other line when answered, no message left when sent to voicemail.

This is my phone number, and it has been spoofed.  That means that someone else is making their caller id look like the call came from my phone.  Please report the incident to the FCC, and then maybe we can help get a law made that makes this practice of spoofing illegal!

It already is
