Can't link with EA

Hello there! So when I try to link the swgoh account I have stored in my device with Ea it won't let me because of a birthdate difference between both accounts. When I set up the old swgoh account on my phone a couple of years ago I introduced a random birth date and I have tried contacting help.ea.com but all my assistants didn't know what to do.

Is there any option to consult my age of the swgoh or change it? 

Thanks!
