After four days of trying almost everything, chatting for about 2 hours with someone from EA, and creating accounts, i finally solved.
I had to download the demo of NBA 2016, tried the demo, this game let me link my account from PSN with the account with EA and then I went to PvZ and it worked.
Seriously, guys... I never had a so terrible experience with a game before....
1) if i bought the Original game for PS, why i have to create a EA account?.
2) if the account is to play online, why it didn't allow me to play offline?
3) Why I have to play a different game to make it work?
4) why I have to need two accounts that match to make it work!!!!!!
I had to apologize to my son on behalf of Santa for not been able to play the game, this is insane...
This is my first experience with one of your games guys, and if honestly probably the last one.
