I had purchased coins 15 days ago and didn't used it all the coins and now after I update the app my all coins are gone and it is asking me to purchase again.😒 even I purchased all the episodes of chankya and other stories and now it is not available to listen due to not premium so, guys before use the app take care of it. Sometimes it seems the owner use the marketing strategy to get money from customers 🙄 so, guys take care of it before use this wrost and wastage of money app. Thank you
