Work through your provider, I would start with you local end.  They should
help you, you ARE their customer.  If not, you need a new provider. Look
into out of band management.

Subject: 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.
