Hey Lucias2010 , are you absolutely sure you are using the same account? If it were the case, your DLCs would be automatically on your account. Are there different emails or usernames you can check? If you ever made purchases through an EA website, do you have any of the confirmation emails in your inbox by any chance? This would give you an idea of which email you should use to login.
If you still don't find your packs or the right account, our help support will be able to help you out with this: https://help.ea.com/customer-care/
