As unfortunate as this outcome was, the docs clearly state that you should have a recovery period of 48 hours (strange the post doesn't mention it):
> Deletion and Restoration
> When a volume is deleted, it is queued for deletion and will be permanently deleted within 48 hours. You can restore the volume during this period using the restoration link sent via email.
> After 48 hours, deletion becomes permanent and the volume cannot be restored.
The question here then, is "is that document correct?"
If it is then I don't see how the volume got deleted - the mail was not sent? The company was not reading its mails?
