since I am no longer the owner of that one. Now if you still didnt understand this or thinks that this is still not an english one, disregard thanks
There's no way to prove that you are not the owner of the account. When did it get hacked? Why didn't you assign an email to the account? And if you did, why didn't you lock the account with the new security feature?
Lots of problems with claiming that your account was hacked as it absolves you of responsibility. Thus people who want to scam can simply state that the account was hacked.
