DOB issues

So, I set up my account about a year or 2 ago, and when I did, I put in that I was born in 2010 and not my real birth year. This has lead to me not being able to change my DOB on EA.com, thus, I can’t purchase the Din Djarn lightspeed bundle because I’m pretty sure teen accounts can’t purchase anything, and I was denied allowance to purchase it, and that’s how I found out I accidentally put 2010. If anyone has experience this issue, please help me.
