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.
If you haven’t already, I recommend checking your Microsoft account for recent purchases or subscriptions using the steps here:
"How to investigate a billing charge from Microsoft" https://support.microsoft.com/account-billing/how-to-investigate-a-billing-charge-from-microsoft-398c5328-364c-d5e4-ea8f-f5ad60562a93
If the charge still doesn’t look familiar, it may be linked to another Microsoft subscription in your household or even a family member’s account. In that case, you can contact Microsoft Support’s billing team directly through that page to review the charge with them and request a refund if needed.
Would you like me to provide you with the steps to contact Microsoft Support via live chat instead?
