Caller Type: Unknown
Phone Number Report: The simplest way to resolve this issue is to send a complaint to the CEO of XO Communications. I looked into this with XO's technical department and unfortunately their records on this # are incorrect. They have an old customer listed as the owner but that customer no longer has the # and they aren't willing to do anything further to stop these calls (like bring the # down). Send your complaints to Carl Grivner, CEO XO Communications, 13865 Sunrise Valley Drive Herndon, VA 20171 - calls will stop immediately!!!
