How do I report unauthorized iTunes charges on my account?

If it were me, the first thing I would do is contact my credit card company to get more information on these charges. Apple really cannot do much here. There are charges to iTunes using the credit card you have on file. Apple cannot stop further charges to that card because you have authorized that card for use on your account. Could anyone else have your Apple account login information? Are there any non-Apple charges to that card?

You can try contacting iTunes support using the steps below.

To contact iTunes Support, do this: 

1. Click on this link --> Choose your country or region - Official Apple Support  

2. Select your country

3. Select: Billing & Subscriptions

4. Select: Subscriptions & Purchases

5. Select: Update payment method

6. Select a chat session or a phone call.
