Hi
I am using the dish tv since a year. but the service provider in not providing the services upto the mark. i am residing at burari, santnagar, delhi. Everyone is fed up of the behaviour and attitude of the service provider. he use to threaten the customers. he even provoke the customers. i am trying to reach the above service provider but he barely picks up the call. whenever he picks the call he says that " do whatever you want to do, but he is not going to change. please help me out.
