Reinstated Anthropic account still says "disabled"

I am an open data science researcher and use Claude and Claude Code extensively. Last week my Anthropic account was auto-suspended. I appealed, and three days later I got an email saying the suspension was an error and that my account had been reinstated.

I still can't log, even a week later (web, app, console, Code). After entering my email, the login screen immediately shows a "Your account has been disabled" message -- no password step or email-link login involved. Automated support tried to clear the problem and I got more "your account has been restored" emails, but the login behavior never changes.

This feels like a "two systems out of sync" situation: Trust & Safety reinstates, but another part of the system still thinks the account is suspended.

Claude is important to my work. I have a lot invested in my existing chats, so I'd prefer not to start over with a new account.

My questions:

* Has anyone encountered this "reinstated but still banned" state? What was the fix?

* Is there any way to escalate for debugging?

Hope this helps someone else as well.
