Locked out of account

Automated captions suddenly completely disappeared from my account, so I contacted support and they told me to try logging out and logging back in.

Then as I tried to log back in, they asked me to verify it’s me. The problem is I realized my account is connected to a number I no longer use or have access to. So I tried using the feedback email and the verification they’re asking for is impossible to answer.

The questions are about what month I made the account, the phone I used, and other questions that are impossible to answer.

Does anyone know what else I can do? I’m desperate at this point.
