How do I get a refund for an unauthorized app purchase on my Apple Account?

And also, it does not appear you have identified what the charge is for, which is the next step to determine if it is unauthorized. Review your Purchase History here:

View your purchase history for the App Store and other Apple media services - Apple Support

For any purchase on your device, it requires double clicking the side button with the amount showing on your screen, followed by verification with FaceID/TouchID or Passcode. This is not something that can be done by accident. If you started a free trial, you will see the trial period on that same screen, along with the subscription you will be billed for if you do not cancel at least 24 hours before that trial period ends. The charge for that subscription will appear on your account after the free trial ends, so that may have been started a month ago. To check if you have any subscriptions, they can be viewed and managed here:

View or cancel app subscriptions on iPhone - Apple Support

Anyone that has your passcode to your device is authorized to use it and that includes for subscriptions. You can also view if you have any other device connected to your account by going to Settings > [name on top], and scroll to the bottom to view other devices on your account. If you have unrecognized devices, you can remove them there and you will also want to change your Apple Account Password.

In most cases, all transactions in the App Store are final due to the secure purchasing process detailed above that requires only information you know, or you have authorized others by giving them your Passcode/Password. In some cases, Apple may provide a compassionate refund, but it should never be expected.

please refund me. because i did not buy any app and click on any apple product. they deducted 3.99 this morning.

Only Apple can decide to grant a refund. Nobody around here can view your Apple Account, nor grant a refund.

If you did not buy, then you will want to re-secure your iPhone, or this can happen again (or worse) due to that unauthorized access..

While you’re waiting for the people that work for Apple to decide whether (or not) to grant a refund for “an unauthorized app purchase”, now is the time to take steps to repair the security breach:

If you think your Apple Account has been compromised - Apple Support

That work includes a new Apple Account t password, and a new passcode, as well as changing the other passwords and passcodes all of which can also be ck promised by your reported security breach.

After following the steps provided in the previous post, you should now know that the charge is for. Being charged this morning does not mean that is when the purchase was made, it is possible you have a subscription and will continue to be billed. If you did not do it, then someone else has your personal information and you will need to secure your account/phone.

Without any further information on these details, there is nothing additional we can provide.
