My phone was stolen; recovery via the second registered email address was rejected saying because the phone is still registered - how can i get access to my Account?

But the Story goes on ...I also created a second Google account using the recovery email and a new, verified mobile number. This account was immediately blocked by Google. I also used the appeal function against the block, but strangely, the post couldn't be sent – ​​an error occurred, please try again. On the next attempt, I couldn't access the account at all. Has anyone else experienced this, and how did you regain access to the account?

I urgently need access because of sensitive data and passwords.
