Delete Facebook account without email.

Hello,

Here I am in a complicated situation... my father has two Facebook accounts, one of which he wants to delete, but the problem is, he can't remember the password, and it's impossible to recover it... because the email address used is that of his former workplace, so he no longer has access... unable to recover the password via "trusted friends" because he didn't activate that. I left a message on Facebook's help page, but no one is responding... I've searched for who knows how long for a way to contact Facebook, but I can't find an email address or a phone number! I managed to find the Facebook France page, I sent a private message, but no response for 11 days... and yet I received an automatic message saying they had received my message. This has been going on for months... my father just wants to delete his Facebook account! I thought I could find a way to send my father's identity card (as is the case for some websites in order to recover an account), but I found nothing either... I can't count the number of times I've gone through Facebook's help pages and Google's searches... I have no solution! If anyone has the solution... thank you for your help!
