I don't think you can delete an org while there are still devices in the inventory... So the org is probably still there See this excerpt from the docs: Before an organization can be deleted, it must meet the following list of requirements: Organizations can only be deleted by a full-access organization admin. There can be no other users on the organization (under Organization > Configure > Administrators), other than the one organization admin. Note: This includes disabling SAML authentication if it is enabled. All networks have been deleted from the org. Please note that because networks with billing transactions cannot be deleted, organizations containing these networks cannot be deleted. There must be no devices left on the org; all devices need to be removed from networks, and the organization inventory must be empty. There must be no licenses left on the org (under Organization > Configure > License info). Please reference our documentation for more information on Moving Licenses. If you've lost access to the organization you'll have to go through helpdesk to get access to it again. You'll very likely need to provide proof that you actually own the hardware. That's why people who buy second hand hardware always need to verify that it was indeed unclaimed first. And it's also the reason why the dashboard complains when there's only one org admin in an organization. If anything happens to the email or the person, you can't get access to the org anymore (at least not without a longwindy process).
