@Christopher Blignaut
Thank you for your post!
When it comes to Azure MFA, did you ever add an alternative method to sign in to your account, such as through your office phone, Microsoft Authenticator app, etc.? If not, unfortunately, you'll have to either get your phone fixed so you can log in or reach out to your organization's Help desk for assistance.
You can also try changing your verification methods using your MyProfile page to hopefully help with signing in.
For more info - I don't have my mobile device with me
Thank you for your time and patience throughout this issue.
