Not recieveing emails from swtor cannot recover display name
I played this game last year or so and I know I have an account. However, I cannot recover my display name as I am not receiving any emails from the service when I try to recover it.

I hope you know the e-mail address that you registered the account with because otherwise, it will be impossible to get back access to it. Once you know the e-mail address, you can call Customer Service by phone; they can tell you your Display Name or get your e-mail address working again. For phone numbers, see https://help.ea.com/en/article/swtor-support/ and you can use Skype to save on expensive international calling costs.
By the way, try checking your older e-mails; usually SWTOR includes your Display Name in their e-mails so you may be able to find it out that way.
