Hello! If you have your game ID then yes you'll be able to get it back! The only possible way to get your account is to contact Bandai Namco's support page. Just follow these steps and you'll most likely be fine. (I suggest waiting a bit untill the tumblr updates the guide since I see some missing parts that I myself do not understand.)

About setting up a new account, since you know how everything works, I suggest saving your transfer code of your new account and then using the Aikotobas and wait untill the Aniversary Gacha comes up as that'll retrive most of the cards from your old account if you don't get it back.

Good luck on getting your old account back!
