Hi, I'm John! I will help you with this.
Microsoft Q&A is public, and we can only provide information. It is beyond our capability to assist directly with billing-related concerns.
To get a refund for your Microsoft 365 subscription, you'll need to cancel it first, and then you may be eligible for a refund for the unused portion of your subscription:
- Go to https://account.microsoft.com/services
- Sign in with the Microsoft account you used for the subscription.
- Look for your Microsoft 365 subscription and select "Manage".
- Then choose "Cancel subscription" and follow the prompts.
Once it's canceled, you may see an option to request a refund, if you're eligible, it’ll appear there automatically.
