Here is some advices that can help you:
Check Purchase History: Go to your iTunes account settings to view your purchase history. This can help you identify any recent purchases or subscriptions that may have been made.
- Open iTunes or the Music app on your computer.
- Click on your account name or sign in.
- Go to Account Settings and look for Purchase History.
Apple ID Subscriptions: Even if you don't remember signing up for anything, check your Apple ID subscriptions. Sometimes free trials can lead to charges if not canceled.
- Go to Settings > [Your Name] > Subscriptions on your iPhone or iPad.
- On a computer, sign in to your Apple ID account page and check the Subscriptions section.
In my view, this kind of problems do not come up without any backgroud. Most likely you subscriben on something by mistace and forogot about this.
Hope, you will solve this problem :)
