Hello, good day and I am here to help you out. Sorry to know on what happened for this PC Game pass subscription charge that is tagged against your account.
If there is no other order or subscription that is present on your account this means that the payment method or the card that you are using got caught somewhere from the last time that you have used it and this has caused an unauthorized charge and in this case 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.
