All payments are processed by Google Play or the App Store — not by Asha directly. To request a refund, go to your purchase history in the Play Store or App Store and select "Request a refund". If you need further help, describe your situation below.
Try closing and reopening the app. If the issue persists, open the subscription screen and tap Restore purchases, next to the legal links at the bottom. Your subscription is tied to your App Store account, so it follows you to a new device.
"You can cancel directly from the Play Store (Android) or Settings > Subscriptions (iPhone). If you still need help, describe your issue below."
