As per the latest condìtions of trai, i had selected channels of my choice on the airtel dth. As per the directions on tv for selection of channels, i had selected the channels and had sent the qr code as sms to the airtel number. I had received a confirmation message from airtel. I received another message that my request has not been processed.
