Hi

To check your iTunes Store purchase history (including iTunes, App Store and iBooks Store purchases), follow the instructions here:

• See your purchase history in the iTunes Store on a Mac or PC - Apple Support
• To request a refund, click on Report a Problem next to the relevant purchase.

Keep in mind that, if you are the family organiser under Family Sharing, you will be billed for purchases made by family members.

You may have an active subscription or membership. If so, to view them - and to turn off Automatic Renewal  - follow the instructions here:

• View, change, or cancel your subscriptions - Apple Support

If you then still wish to contact Apple Support by telephone, contact numbers are available here:
