Hi anonymous user Thank you for the details and apologize for the delay in getting back.
Well, I see that we have a lockout scenario here and I would like to suggest you to open the case calling the support - https://learn.microsoft.com/en-us/microsoft-365/admin/contact-support-for-business-products?&tabs=phone or you can also open a support ticket to get Microsoft Data Protection team engaged for this issue. After providing required information and evidence to prove the company ownership on the subscription, they can help you with migrating the subscription to the company owned directory.
