requesting refund

To request a refund for the charges on your card, you will need to follow the steps outlined by Microsoft. Since you mentioned that you did not authorize these charges, it's important to act quickly. Here’s what you can do:

1. Contact Microsoft Support: You should reach out to the Microsoft Billing team directly. You can do this through the Microsoft 365 Admin Center if you have admin access. If not, contact someone in your organization who does.
2. Submit a Support Ticket: Log into admin.microsoft.com with your admin credentials, select the help & support button, and then search for "I need to update billing information". From there, you can choose to contact support and describe your issue in detail.
3. Follow Refund Procedures: You may also find specific instructions for requesting refunds on the Microsoft support website, which can guide you through the process of getting your money back for unauthorized charges.

Make sure to provide all relevant details about the charges when you contact support to expedite the process.
