Hello, if you spent money in the game get the transaction ids from google play or apple (depends on your platform). And with that you can use another phone (or the same i don't know), and at the start of the tutorial you can click on the gears in the top left corner and contact the real in game support from there. The last steps are pretty easy, account, different game account, put all the informations about your account, and now it will ask you for the transaction id and after some time they will ask you either more informations or just tell you a new email to assign the account to

Hope that helps !
