First off, the experience you describe sounds incredibly frustrating and I’m sorry you’re dealing with it! I’ll do my best to help out.
After some initial searching however, I was unable to locate a ticket that would have been generated by filling out the Appeal Form you mentioned. It should have opened a ticket with your username/email, but I haven’t been able to find anything. Could you please let us know if there was a ticket ID generated when you submitted your form? You should have received at least an automated response, providing that ID.
Further, you describe that your entire team/org can’t access GitHub at all?
Could you also let us know which Organization is experiencing issues?
It would also be great to understand what you mean about your CI/CD process with Heroku. Are you using GitHub Actions to push through to Heroku? If so, do your workflow runs fail? If not, any other detail about what you’re experiencing would be very helpful in trying to resolve your issues.
