We mainly buy airtel products because it emerged as a big brand and we often think that airtel provides quality and best customer service.But think once before going to airtel dth.The signal quality and even hd quality is pretty good but the problem comes while paying to it.Its too costly and if we opt for the HD channels we cant even bare the bill! and the customer service is worst because we are not allowed to call them or talk to them the entire customer service is provided only via messaging.We have to send messages every time to stop or start a channel which is a time taking and we also get only a limited information
