A charge related to MyTunes may come from:
A subscription starting or renewing.
A trial or introductory offer converting according to the terms accepted at purchase.
An additional credit, song, voice, or video purchase.
Another in-app purchase shown in your App Store or Google Play history.
Check the purchase history of the store account used for payment. If you do not recognize a charge, contact the store first for transaction details and contact MyTunes support with a screenshot or order reference if further product investigation is needed.
To avoid future subscription charges, cancel the subscription through the App Store or Google Play before the next renewal date. Deleting MyTunes does not cancel a store-managed subscription.
