Who called from 2030303200

This phone number keeps showing up on my callrd ID. i do not answer calls from numbers I do not recognize. They are wasting their time!!!!!!!!!

my phone rang and i heard some sort of music and mr. jackson as he called him self ask if i liked the cable i use. i have told him to quit calling. he keeps calling and its anoying.

This idiot called at 1015 pm some weird music blurb and then he said hello, this is Michael.  I asked Michael who?  He replied, your highschool friend.  I hung up...Can we block him?
