Who called from 4438781910

Called my cell.  Some kind of caller that shouldn't be calling. I called the # back (with my # blocked) and got a recording that said "press 9 to be removed from our list.  It will take 72 days for the request to be processed".  Doesn't sound valid to me if the only thing you hear on their recording is how to take yourself off the list.  Already blocked the number.

Rec'd call Friday 8/19/16 1:56 PM. No message.

Never call the number back. They can use that to identify your number as a 'good' number, and sell it or continue to spamcall you.

why do you call my number if you only want to be added to do not call list.  It never ends doies it?
