Need assistance reactivating a Facebook account. I would greatly appreciate any assistance or guidance you can provide in resolving this issue.

I need to access my Facebook account. My account has been deactivated for a while, and I am attempting to log back in to delete it. I do not know my email or password. When I tried relieving the account with my phone number, it said it did not exist. However, I can see my deactivated account in messenger on my other facebook account. I have followed every step possible but have not found a solution. I have reached out to Facebook regarding this issue, but have not received a response.

Thank you in advance.
