Hello KingxBlair, welcome to the Apple Support Community!
This levy can be explained by two main reasons. First of all, most subscriptions must be canceled at least 24 hours before the renewal date, if the cancellation is made too close to the due date, the payment request is already sent to your bank. The charge may also correspond to a different subscription or purchase that you can identify on reportaproblem.apple.com. If the billing is linked to this canceled subscription, you can request a refund on this same site. To track the status of your subscriptions or submit your request, do not hesitate to consult the article Request a refund for apps or content that you bought from Apple - Apple Support. Have a nice day :)
