Unauthorized EA SPORTS FC Mobile purchases cancellation and refund request

To request a refund for apps or content that you bought from Apple, click here → https://support.apple.com/HT204084 Keep in mind that refunds are considered in most countries by Apple to be an exception and you may be refused a refund for some or all requests.

Apple’s position appears to be that people need to be proactive about purchases, canceling subscriptions at least 24 hours before trials end or a subscription renews, and ensuring that others are not able to make unsanctioned purchases on a user’s account. Note that if you allow—intentionally or not—another person access to purchasing on a device, or through Family Sharing if you are the Organizer, you are taking responsibility for things they do. Apple offers these features to help you avoid this situation:

On your device you can use Screen Time to prevent unintentional or unauthorized purchases from the App Store, in-app, and other Apple services. —> https://support.apple.com/102470

Also on your device, require a password for App Store and iTunes purchases —> https://support.apple.com/119848

Use Screen Time as part of parental controls on your child's iPhone, iPad, and iPod touch —> https://support.apple.com/105121

Use Screen Time to turn off in-app purchases on your iPhone or iPad —> https://support.apple.com/102470

If a child made this purchase on their device as part of Family Sharing, consider activating Ask To Buy—> https://support.apple.com/105055

Use Guided Access to permit a person to only use a single app —>

Also, the authorization you have provided for the purchases is the Passcode for the child to use the device. If you don't want those purchases to happen, you have to take the steps to prevent it, either by requiring a password for the purchase or use screen time to disable in-app purchases altogether. Apple has no idea who you have allowed to use your device and since the iPhone is a single user device, you are the one that has to prevent that from happening.

Pending purchases cannot be cancelled. All you can do is let them proceed, then request to have a refund. In most cases all transactions in the App Store are final due to the explicit actions and your personal information required to approve them, but at times Apple may provide a compassionate refund. It should never be expected though, and you can try here:
