If you have any questions, you can always contact EA Support as well via Live Chat, and they may be able to help with your Account. Unfortunately there isn't anything we can do here Account related.
Given that today is Christmas, they may not be there at the moment. However, you can always try tomorrow.
Thanks 🙂
