They say they are the Committee for Missing Children, However CMC is in Lawrenceville, GA and these calls are comming from Bartonville, TX. I had to reaaly press to get any information from these people then they wouldn't take no for an answer when it came to the donation, I finally had to hang up on the guy. They do have a "Do Not Call" option but you have to call 800-594-6135 to request it and it's thru an automated menu so I don't know if it will take.
9402951883 listed as a Dallas/Denton area number. Left no message.
