Who called from 6023997911

Called but didn't leave any messages. Called back and it kept ringing without a voicemail.

this number called twice in a row on my cell.  The first call no one was there and they hung up.  2nd call he asked for Michael.  No one here by that name, so he hung up again

this number called and didn't respond, so i hung up.

Says it's from Arizona but I don't know anyone from there so I didn't pick up.

This guy calls my number and ask for my wife I asked him what it's in reference to ando he  hangs up on me. I've tried to call him back but there's no answer when I dial this number
