I would suggest you following the instructions here :

This signing thing is confusing to me as well. I have never signed my account that got hacked, can it be recovered?
That just means, you ought to have access to the crypto address used by you, before the hacking incident. It helps in identifying if the user is the original owner of the account to the recovery team. ( You can also recover using registered email sometimes, but its case by case)
Hi Fifa, how do i know it is safe to post my stolen account name here. are you trying to help?
It would be more helpful for you if you post your username here, as it will make your account mostly unusable for the hacker due to the red tags. DT's here would act upon it and you can clear it up once to get the account back.
