Additional sign-in or account-related issues within Microsoft Teams for business
Hello R,
Could you please confirm whether you can access the Microsoft 365 admin center using the account that was used to purchase the subscription?
If you can sign in, please go to Billing > Your products, locate the subscription, and follow the official Microsoft instructions below to cancel it or turn off recurring billing: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn
If you cannot access the Admin Center because the account is managed or blocked by the school, please contact the school’s IT administrator. Since the subscription was purchased through an account in the school’s tenant, an administrator with the appropriate billing permissions can locate the self-service purchase, take control of it, and cancel it through Billing > Your products > Self-service.
You can share this official guidance with the administrator: Manage self-service purchases and trials (for admins) | Microsoft Learn
If you also want to request a refund, please ask the school’s IT administrator to open a support ticket through Help & support in the Microsoft 365 admin center and request assistance from the Billing Support team. Please note that cancellation does not automatically guarantee a refund. Eligibility depends on the billing agreement, purchase or renewal date, region, and subscription terms.
If the school cannot assist or open a ticket, you can contact Microsoft directly through the regional numbers listed here: Customer service phone numbers | Microsoft Support
When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.
I also recommend calling during business hours. In my experience, it can be difficult to get through to the correct support queue, and automated systems don't always work as expected. If you can't get through on your first try, I suggest trying again later or at a different time.
Please explain that the subscription is linked to a blocked school account and that you need help cancelling it and reviewing refund eligibility.
Kind regards,
