Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello @Didier @ Singapore
If you purchased a subscription and canceled it within a short period of time, I recommend contacting the Microsoft Billing Support team to inquire about a refund. The support team will review your subscription details and determine whether you meet the eligibility requirements for a refund.
You can find the steps to contact support in the following article: Get support - Microsoft 365 admin | Microsoft Learn
When opening a support request, please make sure to disable the Support Assistant (AI) in the help panel first. Then enter a brief description of your issue, such as "Inquiry for subscription refund." Once the AI assistant is turned off, the Contact Support option should appear, allowing you to submit a support ticket directly to Microsoft's support team.
Please give this a try and let me know if you need any further assistance. I will be happy to help.
