Twitter Two-factor Authentication Code Error, No Way To Gain Access Back

I haven't forgotten my Twitter password. However, even though I didn't enable two-factor authentication, it asks for a verification code when I try to log in. I can't access my account without the verification code. I have created multiple support tickets, but the response I receive redirects me to the login page. It's frustrating that I can't even tell them it's my own account. My username is @ket0ke, and I've been using this account for years. When I send an email to the help center from the email I use to log into my account, they respond saying that the email doesn't belong to my account. I feel like they're really joking w me. I urgently request assistance. My issue has been unresolved for about a month. I'm requesting that a login code be sent to my associated email or phone number.
