Brawl Stars-I’ve received a bill for a purchase I didn’t make. What should I do if I suspect fraudulent activity?-[English]

If you or your child have never played one of our games, but suspect that there’s been fraudulent transaction activity on your account, then you should immediately contact Apple (for iOS devices) or Google (for Android devices), who control the transaction process.
For Apple (iOS) devices:
Visit Apple support and select the "Contact iTunes store support" link, then "Purchases, billing and redemption" and choose the option that fits you best.
For Google (Android) devices:
Visit Google support and perform a search, or use the ‘Contact us’ button on the page (English language site only) to reach a Google customer support representative by email or by phone.
If you’ve already contacted Apple or Google about suspected fraudulent activity and they’ve sent you to us, please contact us at Be sure to include specific details like what happened and when, transaction ID receipts, relevant screenshots, etc.
