Community ManagerRe: Link two EA accounts with different emails together
Generally you'll need to wait for the timer, however if the wrong account was linked you can reach out to support to see if they have any other options available.
If you create a new case here and select Game Support > The EA app > I want to update my EA Account information, you should be able to get in touch with the support team so they can take a look.
