Cogent Abuse - Bogus Propagation of ASN 36471

NANOG, A customer of Cogent has a compromised router that is announcing prefixes sourced from AS 36471.   Cogent is propagating that to the world.  Problem is, those prefixes and AS don't belong to that customer of Cogent - AS 36471 belongs to Kratos Defense & Security Solutions, Inc. (see whois). Requests to Cogent Support and Abuse go un-actioned.  Need a contact at Cogent Abuse that can shut down that compromised router.  Anyone have a good contact at Cogent Abuse Dept?
