No access to account's e-mail address
I have a problem with signing in to my TV account. I'm currently abroad and when I try to log into my account on another PC i keep getting error saying "Please check your inbox for the email we sent you and follow the provided link. We could not verify if your account has been used on this device before. To sign in on this device you need to add it to your trusted devices." The problem is that email address used to sign in no longer exist.
Can I confirm ownership of my account on some other way?
