Solution 1Recommended

Contact Microsoft Support Directly

The most effective way to resolve billing issues and request refunds is by speaking directly to a Microsoft Support agent.

Because account and refund issues involve private billing information, they cannot be resolved on public forums. You must verify your identity with official Microsoft Support.

Visit the Support Page

Go to the official Microsoft Contact Support page in your web browser and sign in with the Microsoft account associated with the charge.

Access the Get Help App

Type 'Unauthorized charge' or 'Talk to an agent' in the search bar to bypass the automated troubleshooting articles.

Select the Billing Category

Click the 'Contact Support' button at the bottom. Choose 'Microsoft 365 and Office' as the product, and select 'Billing and Account Profile questions' or 'Subscription Issue' as the category.

Choose a Contact Method

Select the option to 'Chat with a support agent in your web browser' or request a callback if phone support is available in your region.

Menu Options May Vary: If the exact 'Subscription Issue' category is missing, select the closest available billing category to reach a live representative.

Solution 2

Dispute the Charge with Your Payment Provider

If you suspect fraud, cannot reach Microsoft, or if Microsoft refuses the refund, you should dispute the charge directly with your bank.

Frequently Asked Questions

Why was I charged $792 for Microsoft 365?

A charge of $792 typically corresponds to an annual Microsoft 365 Business Premium subscription for multiple users. If you only had a $99 Home subscription, this suggests an unauthorized upgrade, an account compromise, or a billing error.

Can I get a refund for an unauthorized Microsoft 365 charge?

Yes, Microsoft generally issues refunds for unauthorized subscription upgrades if you report them promptly. You must contact their billing support directly to verify your identity and process the refund.

Why can't I find the billing category on the Microsoft Help page?

Microsoft frequently updates its support interface. If the specific 'Subscription Issue' category is missing, try typing 'Talk to a person' in the virtual assistant chat to bypass the automated categories and reach a live agent.
