Check this first to see if you can see the exact nature of these charges:
The support article "If you see 'apple.com/bill' on your billing statement" explains how you can check your iTunes and App Stores purchase history, cancel subscriptions, and track possible sources of unrecognized Apple charges you may see on a bill. These may be purchases by family members if you are an organizer of a Family Sharing group, or possibly a second Apple ID you use. The article also provides a specific link for contacting Apple if you cannot trace the source of charges. Click on this link to read this article ➞ https://support.apple.com/HT201382
Other possibilities to consider (not all may apply in your situation):
- Purchases can be made with your ID if your Apple ID is compromised (what to do ➞ https://support.apple.com/HT204145 ) or somebody else has access to your device (require purchase password ➞ https://support.apple.com/HT204030 ).
- If you only see a charge in emails or texts that are not official Apple receipts, it is likely phishing attempts ( https://support.apple.com/HT204759 ).
- If you are absolutely certain neither you, nor Apple, nor a Family Sharing member can account for a charge and it ONLY appears on a bill for a charge card you alone control, you may have been the victim of card fraud. Contact your financial institution.
If you think you have truly been billed twice for exactly the same item contact Apple to help you with this. If you use the usual methods for asking for a refund this may result in a cancellation of the service or app and loss of all data associated with it even if you only wanted a refund for the second billing and intended to keep the item.
