If you purchased your subscription through the App Store, you need to contact Apple Support directly. Here are refund instructions you might find useful: https://support.apple.com/en-us/HT204084. We wish we could help, but only the App Store can manage refunds for the purchases made with Apple iTunes accounts.
If you purchased your subscription through the Google Play Store, please send us your payment receipt at firstname.lastname@example.org within 30 days. You will find it in your inbox by searching for ‘Google Play Store.’ As soon as we have the transaction number from your receipt (starting with GPA), we will be able to refund the money. You’ll see it back in your bank account in 3–10 days.
Please note, we make refunds for the ‘12 Months’ subscription plans only.
