Hello, good day and thanks for your question. Sorry to know about this and I understand that you have encountered an unauthorized charge on your account.
It is best to cancel it under account.microsoft.com/services and check if there is also a refund option that will show up.
If there is no option that is present on your account, it is best to reach out to the bank to block and replace your card to avoid additional or future unwanted charge/s. It is also a good measure to temporarily lock it from the bank's website or the bank's mobile app as soon as possible and request for a refund from the bank from the fraudulent charge that happened.
