Lost Super Admin Access

I am a new volunteer trying to update the Africa Bridge website. Our organization has had some turn over and we no longer have Super Admin access to our WordPress site. We are using BlueHost. They are also unable to authenticate us so we are dead in the water. We want to keep using the WordPress blog, but redirect the rest of the site to a new site created through Aplos, our fundraising software. Since we can’t get to settings we can’t do anything about the URL via subdomain. When people click on https://africabridge.org/ we want them to go here: https://africabridge.aplos.org/ Any suggestions would be greatly appreciated.
