Try as much as possible to provide data and add information that the hacker cannot know.
It will not be easy to restore this account. Because it is unknown how deep the hackers penetrated the account. What if they accessed the email, the private wallet keys, and anything else that can be accessed. Maybe this person's computer was hacked and the hackers accessed everything that was possible.
