Problem with lords and knights

iOS & iPadOS Gaming

Hi, I have unjailbroken my iPhone and restored it, then when I entered into lords and knights all of my account was gone. But in gamecenter I can still see my achievements and stuff. My friends can see my previous account in alliance too. I didn't connect the game via facebook. please can somebody tell me how to log into my account? I didn't connect to it via e-mail either. Thank you.
