This number has called me numerous times and days, but they never left messages.

This number has called numerous times today and called other days as well.  They did not leave any messages.

Called me and my caller ID showed +1 224-970-1992 +(my own number) and my name. It then doesn't show up on my metropcs call blocker except as my name and number. (I got this number from my caller ID.)
Accidently called myself and my voicemail asked for a password. Or did it? DEFINITELY A PFISHER/SCAM.

called twice in a row, unknown caller, no message. added to the blocked and spam list

THESE PEOPLE GET ON MY DAMN NERVES!!!!!!!!!!!!!!!!!!!!!!!!!!!
