I had an unused account just to save my real name handle, and haven’t been able to log in to delete it either. It says it’s texted a code to my 2FA phone # (confirmed to be the correct #), but I never get the code. I’ve been trying since before Elon took over. I’m so sorry this is happening to you.

1. create a new account.
2. report the old account for impersonation.
Good luck.
