Re: Lost My Account
Did you sign up to EA's email registration scheme?
If you did then you can get a code sent to your email address to restore your old account.
Is pvz2 on an old device?
If it is, then try disconnecting it from the internet and access the old version and screenshot your old player id number.
Unfortunately, EA can't/won't recover lost accounts without the correct player id number and are too stupid to tell players to keep this all important information safe.
If you haven't signed up to EA's email registration scheme or have the correct player id number, then the only thing that you can do is contact EA help and provide them with screenshots of your purchase history and any proof of plant levels so they can add them to your new account.
