Who called from 2040000000

a blank call...just rang once or twice..like a missed call n wn answrd no one was answering..

a lady calling from this number keeps asking for my minor son (by name), I ask who is calling and she indicates she can only reveal her identity to my son......

My thoughts are.....if this lady can't tell ME my son's guardian who or where or why she is calling then she will never speak to my son.....who is this and why are they calling???? HELP!

I always screen calls...received two calls from this number today.

just saw this # come up on my cell phone....NEVER seen a # like this b4 & sure would like to know where this # is coming from???

What is this number? I didn't bother answering thinking its a scammer
