reset microsoft account password not working

I need to speak with a live person regarding my other microsoft account that I can't login and the process to reset password is not working so I'm stuck because when I try to reset the password, it sends a code to my email and when I type the correct code it is asking to check my Authenticator code but the app is not working since I've replaced my iPhone and none of the online methods help and I can't speak with a person. Very frustrating.
