Can't log in to real account

I can't log into my real account. I made this account solely because I need to contact customer support to help me log in. I have the username and password to my real account. I don't have an authenticator app, nor do I have the recovery code. I reset my password to make sure I have the correct password, which I do, but I can't log into my account because I don't have a way of performing two-factor authentication. I need help resetting my two-factor authentication on my actual account.
