Unable to Confirm Facebook account identity on another computer

Hello, I'm so sorry because my English is not good.

My Fb is hacked at 5am, I received my email that someone changed my password, deleted trusted contacts. When I try to login I recognize that they change my email and delete my phone number too. Then I started securing my account by clicking a link Fb emailed me. I choose 4 comments in last 3 months, its correct so Fb allow me to change my password. But its not enough, the problem is that Facebook continue asking to secure my account after

1) To finish securing your account, please verify your identity and change your password. Your account will remain hidden until you complete this process.
2) Choose a Security Check
How do you want to confirm your identity?

- I have an unlock code ( but I checked my email and I don't find any code, I think it send to email's hacker)
- Ask your trusted contacts for help ( I think hackers make something here because my email said they deleted but why my friends is still trusted contact? And when my friends do what I said they dont have any code, FB said they are not trusted contact, but I dont understand why FB asked me to contact them though they are not trusted contact)
- Confirm your identity on another phone or computer*

To continue, please confirm identity on a phone or computer you've used before.

The funny thing here is that when i try to login on this device which is MY PHONE (in the list exaclty the time I USED BEFORE) facebook keeps telling me the same thing as list 1) section.

Finally, when I cant do anything, I recover account. FB asks me for an ID but the account has a fake name (THU THẢO) and my real name is LÊ THU THẢO and I dont set my birthday too. So when I send all real id and other documents to facebook they email me "Hi,

We can't help you with your request until we've received an ID or other documents that we can use to confirm that you're the owner of this account. "

SO what I can I do now?
