Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, Please sign into your Microsoft account here: https://go.microsoft.com/fwlink/?linkid=2246882 You should find the Investigate charge option on the upper right to start the process, and select this charge to submit an investigation request to Microsoft billing support team.
If the charges are not in your account, but in your credit card statement, it's possible that your credit card has been compromised. This means unauthorized charges may have been made on someone else's Microsoft account using your credit card. In such a scenario, you should contact your credit card company to open a dispute case. Microsoft is unable to directly investigate issues related to someone else's account if you contact their Billing Support directly. However, once a dispute case is initiated by your credit card company, Microsoft can then respond specifically to those claims through the dispute process with the credit card company. This is the appropriate channel to resolve such issues, as it ensures proper verification and handling of the unauthorized charges.
