I do not know which Microsoft account a subscription is attached to.

Hey there! Nice to meet you!

You may follow the guide on the official Microsoft website to investigate and locate the subscription charge from Microsoft on this link:

If you're able to find the transaction, you can check if it is eligible for a refund through this link:

You may also try contacting Microsoft Support for further assistance in tracking the transaction:

https://support.microsoft.com/home/contact?SourceApp=smc2&ContactUsExperienceEntryPointAssetId=S.HP.SmcContactUsLanding

Type "Billing Issue" > click "Get Help" > Scroll down to Sign in to Contact Support > Microsoft 365 and Office > Billing and Payment Updates > Confirm > Chat with a support agent in your web browser

If you and the Support Team are unable to find the transaction in all of your accounts, you'll need to contact your financial institution/bank directly to dispute it, and they may process a refund, as this would be considered a fraudulent charge.

You may also need to have your card blocked and request a new one.

Thank you for your understanding! Please let me know if you need anything else.

Best regards,
