The final page to submit won't load to allow me to choose an option to verify identity. I have an intl phone number, so I can't access a human to help. Terrible service

There is a bug in the site, I have already read through the community articles on what to do if a page doesn't load, but none have helped or are applicable. I have been going in circles between the phone bot and the answer bot online, and cannot reach a human. I live abroad and have an international number, so I can't get the bot to call me back because it won't accept any number that isn't American.
