It's a hard lesson to learn like this, but it's a learning moment nonetheless. You don't rely on your provider to make backups for business-critical stuff like this, you need to manage it (and test!) it yourself.
rclone[1] supports tons of storage providers. If you get access back and recover your business, start making backups onto other providers.
I would say the lesson is just use AWS which has outstanding support. Building backups yourself, going multi cloud or else just erase the benefit of CF. If you do this you can just run on a bare metal and save on cloud cost.
