When you are eligible to update your account, you will receive an Origin notification each time you log in.
If you fit here- players in Ireland must be 16 and players in Australia must be 15 and in other countries for up to 13 years to update to an adult account- I do not see why you could not change 🤔
Have you tried this steps to Updating a child account to an adult account ?? And didn't work?
Maybe you have the wrong year of birth in Origin? 🤔
Then the only way to resolve ,you need to create an incident using the Talk to a Game Advisor link on the left, and a Game Advisor will assist you.

Your suggestions didn't work and no, I did not put in wrong date of birth. But, there might be a chance it said "Your account will be a child account until you reach 16 years of age" or something like that. Although I do not live in Ireland nor Australia. I live in Sweden. Nothing here in the web says I have to be 16 years or older to access online features..
