I'm not happy with FBReader Premium and want to refund. Is it possible?

We are sorry that you are not satisfied with the app. You can refund via the Google Play site. Please read their support page. You also can send a request to support@fbreader.org. We do refund for a purchase made no more than 30 days before the request date. Please send us your purchase id (a string like GPA.123-456-78910). To find it, look at your purchase history. Our support is not 24/7, so please be patient.

Please note that if you make a refund, it can take some hours (or even days) until the money reaches your card/bank/etc. The time depends on your bank, not on Google or us.
