Expired family member account delema

Hi folks I'm a member of a familiy plan that recently expired. I have no way to contact the family plan owner nor could I activate the plan myself. I've contact the IT for deletion and they said there's nothing they can do because the account is frozen due to expiration.

Please help me understand why I cannot delete my own data. And being a 1Password user who cares about privacy, I'm really not comfortable leaving my data stuck there unattended.
