Hello. After a free trial of Microsoft 365 Business, I was automatically converted to paid and paid for one month.

Immediately after payment, I sent several refund and cancellation request emails, but I didn't receive a response.

Currently, the administrator account is unknown, so it is impossible to log in itself.

I would like to ask if there is a way to verify my tenant domain or administrator account.

Also, please let me know if there is an official process to proceed with a refund request while you are unable to log in.

Thank you.

    Hi White017 Ethan

    Base on your description, please contact Microsoft Support directly. They will need to verify ownership of the Microsoft 365 tenant and subscription before they can discuss account details or evaluate a refund request. At the same time, you may request assistance with recovering the administrator account. (Microsoft 365 Business Support: https://support.microsoft.com/contactus)

    To refunds are handled for business subscriptions, please refer to Cancel your Microsoft business subscription.

    Or you can try to contact them via phone service number: Customer service phone numbers - Microsoft Support. The agent will be able to create a ticket for you.

    In some case the phone line is not supportive, you can consider directly submitting a support request as a helpful workaround:    

    • Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.    
    • Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your affected tenant.  
    • Select the Help & support (headset) icon. If Support Assistant is enabled, turn it off > Type contact support in the search box > Select Contact support, then choose Phone or Email to submit your request.    

    Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with multi-factor authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.     

    For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.
