If you prefer a somewhat more descriptive list that includes a few reasons and solutions not mentioned in the article posted earlier:
The support article If you see 'apple.com/bill' on your billing statement - Apple Support 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. If you use Apple Card you may find this document helpful too ➞ If you see an Apple Services charge you don't recognize on your Apple Card - Apple Support
Other possibilities to consider (not all may apply in your situation):
● Purchases can be made with your ID if your Apple ID is compromised (read what to do ➞ If you think your Apple ID has been compromised - Apple Support ) or somebody else has access to your device (require a purchase password as explained in this article ➞ Require a password for App Store and iTunes purchases - Apple Support ).
● If you only see a charge in emails or texts that are not official Apple receipts, it is likely phishing attempts ( Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support ).
● 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.
● Small amounts of ~$1 may be an authorization hold that will be refunded (pending charge ➞ How apps, content, and subscriptions from Apple are billed - Apple Support ).
● Unanticipated amounts may be grouped charges ( How apps, content, and subscriptions from Apple are billed - Apple Support ).
If a purchase is listed in your purchase history and you want to ask for a refund, read this article about how to request a refund for apps or content that you bought from Apple ➞ Request a refund for apps or content that you bought from Apple - Apple Support
If a Family Sharing member made the purchase then you need to discuss this with that person. They would have to initiate any refund request.
If a reporting a problem request is unsuccessful or you have another issue you can also speak with Apple ➞ Choose your country or region - Official Apple Support Select your country, then a product.
