Who called from 2150000000

this number appears on my caller id but they never talk.  I kill them I blow them AKKKMED

Three calls from this number today.  Only silence from the other end.

How can this number be legal??? These people call every hour on the hour, never leave a message. I REFUSE to pick up my phone for numbers I do not know. Also WHAT GIVES I have placed my number on the do not call list 3-4 times within the last 3 months. My number was listed on the DNC list when it first came out yet I still continue to get crap calls like this. Why doesn't DNC list work????:!!!!!!

Reported this number and all numbers that we get that are not legit to the do not call list

submitted number to do not call list
