If you wish to receive a refund for PokéCoins you purchased, please contact Apple Support (iOS users), Galaxy App Store (Samsung users), or Google Play Help (Android users) to review their respective refund policies, request a refund, or to inquire about a recent transaction.
Some app stores can only provide refunds within a limited time window, so try to submit your refund request as soon as possible.
Please note that app store refund policies may vary based on the location of user and the age of user, including legal minority, at the time of purchase, as may be required by applicable law.
