Login issue

I can’t login to my plants vs zombies 2 account because the birthdays on the game account and email do not match. I don’t know what birthday is connected to the game account since I got the game close to ten years ago and I don’t think there’s a way to check. I have access to the email.

i created the email and account today on a device with the original Apple ID with the game data.  Now im trying to login to the account on a different Apple ID device
