Long long time ago, I had a similar issue that could not get resolved through normal escalation means.
I ended up going on linked in and grabbing every executive and senior email contact I could find and notified them.
Issue resolved in one day. Nothing gets a nocc moving fast like execs asking about random network issues.
This company was nowhere near the size of Ticketmaster though.

Based on experience, all I can say is good luck. They do not respond to anyone.

We have address ranges that are being blocked by sites like Ticketmaster. Customer support is able to assist, and unable to receive a response from legal or hostmaster emails. What are the recommendations for requesting a removal from the
blocked list at these sites?
