Hi @Leon Reddy
Thank you for posting your question in the Microsoft Q&A forum.
First, I am so sorry about this inconvenience.
Please double check in your Manage subscription to see if you accidently bought 2 licenses. (https://account.microsoft.com)
If that's the case, you can cancel it and refund.
How to get a refund on a Microsoft subscription - Microsoft Support
If you only bought once and got charged twice, I recommend contacting Microsoft Support for Personal Accounts through the official support page: Contact - Microsoft Support Please ensure you're signed in with the correct account associated with the billing issue.
Once you're on the support page, typed "billed twice" and then select "Contact Support" as below picture.
In contact support page, choose the appropriate category to connect with a billing support agent via chat as below.
If you are holding business account, please contact the Office 365 support team by submitting a service request. Here’s what your Office 365 Global Admin should do next:
- Submit a Service Request: The Global Admin should create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin | Microsoft Learn.
- Find Your Microsoft 365 Admin: If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support
- Call Microsoft Support: For additional assistance, use this link to find the appropriate contact number: Customer service phone numbers - Microsoft Support
I hope you will be able to refund.
