Need Help Getting IP Unblocked by AT&T

I'm not sure where to take this issue.  The Regular AT&T NOC contacts
are refusing to talk to me since I do not have a circuit ID, and do not
seem to have any understanding about transiting issues.  I am unable to
fully monitor and manage a router I control, as all traffic bound to its
lan IP that transits through the AT&T network is blocked.  The Router is
connected to a Verizon circuit, but any connection that transits through
AT&T is blocked.  The ip in Question is from a direct ARIN allocation
that I control.  I have attached a ping demonstrating that I am
receiving an ICMP deny from an AT&T core router.  I have also attached a
traceroute to both the offending IP and the WAN IP which appears to be
working.
