Huh? That sounds very, very weird. Did this come in an email by chance? If it did, DO NOT click on any links in it. To cancel subscriptions from Apple, see this article: View, change, or cancel your subscriptions - Apple Support
I would contact Apple Support and read through the information here: Get help with an item purchased from the App Store, iTunes Store, or iBooks Store - Apple Support
Question: Why i don’t have the ‘cancel’ option on my subscription?
