Independent Tv - TV Channels stopped and disruption often

I had taken a two year all channels package with further * years of free channels (total * years) by paying the full subscription amount for * years. Its now little more than a year and the Independent TV (earlier BigTV from Reliance) have failed to broadbast channels regularly. There have been intermittent stoppage of channels running to months without any relay. We missed to watch entirely the IPL **** and world cup **** matches due to this. They take out certain channels without any notice. They dont even tell us when the services will be resumed. Their customer care is very pathetic and keep promising resumption of TV channels in next **-** hours but the promises are never kept and are for months together the channels are not broadcasted. I am really fed up and request the suitable authorities (TRAI ?) to take up these matters with Independent TV who are playing with lakhs of subscribers by collecting money and not honouring to provide services. I am really helpless as I dont have any clue as to who to contact regarging the issue and get the whole refund from them for disruption of services. please help me resolve this issue as I am stuck with a very bad service provider like Independent TV (formerly BigTV)
