We'll be able to help you either if you send us your request from the email address that is associated with the account you're asking about, or if we have any other evidence that the account belongs to you. Otherwise it would be not secure to complete your query.
Correct.That makes sense.If that's the case,it's highly probable OP is a scammer.
Otherwise,you can check the past addresses where the withdrawal was requested and ask him to sign a message from one of them ?
