How to Reach NPM Support? (Sound of Crickets)

We are trying to reclaim an NPM scope that is the same as our company name, and that we have the registered trademark for. I’ve created two support tickets, but weeks have gone by with no response. There appears to be no way to phone, email or otherwise contact NPM support. How do I get this resolved?
Tickets #1344076 and #1391210
Thanks, Cameron
