Hi,
Log in to all of your Microsoft accounts and check if you can see the charges there. https://account.microsoft.com/services/microsoft365/billing
If not, have you asked a family member if they may have used your card in the past?
You can refer to this article: '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 you can't find it, it's possible that your credit card has been compromised. In this case, you’ll need to contact your bank to open a dispute ticket. Your bank should block the charges and may issue you a new card to prevent further charges.
