Used Airtel payment Bank to pay my electricity bill (bescom). The app asks for the customer ID through which it fetches the electricity bill automatically. It showed 1866 rupees which I paid. Then later understood that the actual bill value was 891 rupees from receipt from the electricity board. Paytm also showed 891 rupees. Have sent all the screenshot to [protected]@airte... But they don't give any proper response.
