Incorrect date of birth prevents use of webstore

The date of birth on my SWGOH account (underage) is different to my Ea account(over 18) and also incorrect as I am  over the age of 18. Due to this my SWGOH account has been flagged as underage and now I am unable to access the webstore. I cannot change the date of birth of my SWGOH by myself, where can I get help? My ally code is 556-852-573
