Hi Marlous,
Check the Subscription Type
If the subscription was purchased directly from Microsoft → cancellation must be done through the Microsoft 365 Admin Center or via Microsoft Billing Support.
If the subscription was purchased through a partner/reseller/service provider → only the provider can cancel it, not Microsoft directly.
Because the Original Admin Left
If the employee who set it up is gone and their account/phone is terminated, you need to:
- Log into the Microsoft 365 Admin Center with a Global Admin account.
- If you don’t have one, request an admin takeover of the tenant via Microsoft 365 Admin Takeover
Contact Microsoft Billing Support
Go to https://admin.microsoft.com → Support → New Service Request.
Or call Microsoft Billing Support directly (country-specific phone numbers are listed: https://learn.microsoft.com/microsoft-365/admin/get-help-support
Provide:
Customer number: 0107494759, Proof of your company ownership (domain name, company registration if asked). Evidence of the May 19 cancellation email.
If Subscription Was via a Provider
Microsoft will direct you back to the service provider.
Contact your provider’s billing department with the cancellation request (include your previous email from May 19 as proof).
Request escalation if they don’t respond.
Escalation Option
If neither Microsoft nor the provider responds, you can open a formal escalation through Microsoft:
Go to Microsoft Complaint/Service Escalation Form.
Submit details including your cancellation attempts.
