No Mail and no Security Key..

Game: SWTOR

I've been playing SWTOR since the Beta. Unfortunately, the email I used to register is no longer active and has been lost. To make matters worse, since I changed my phone, I no longer have the security code app with me, and I now find out that it no longer exists or is not updated with current phones. Therefore, I am blocked, I don't know how to access. I still have my password and username, but I can't have the code sent because it goes to the email and that is inaccessible, and I can't put the security key because the app no longer exists. What should I do?
