perdí acceso a mi antiguo número de celular y deseo cambiarlo a mi actual número

This translates as:
Hello, I lost access to my old cell phone number, and although I can log in because I still have the email address I used to create the account, I can no longer add more security to protect it. Could you please verify my information so I can replace the old number with my current one?
