retrieve facebook page

I am looking for a freelancer to retrieve a Facebook page for me. I do not have any access to the page and will not be able to provide login credentials. I need to retrieve the Facebook page because the admin of the page was working for us, and when he left the work, he refused to provide us the information to access and control the page .

Ideal skills and experience for this job include:
- Proficiency in Facebook page control and retrieval
- Experience in handling situations where access to the account is lost
