First, we recommend checking your App Store / Play Store purchase history and the relevant bank statement(s) closely. There have been cases where charges that seemed to come from a single Bunpo purchase were actually several charges, both related and unrelated to Bunpo, that were all authorized by the user and appeared as one item on the record.
If there does seem to be an error and you were charged incorrectly, please request a refund as soon as possible:
For iOS: Request a refund via the App Store.
For Android: Request a refund via the Play Store.
