Independent TV — complaint regarding tv channels

Dear sir,
Since a month, one by one each and every channel is not working. I just can't see any show and they just show "we regret the inconvenience being caused due to non availability of this channel. We are working on the resolution and shall resume soon." it's been a month and i can't see any show. Channels like zee tv, colors, mtv, and many more are not coming. We just installed independent tv in january and it started giving us trouble in march. What kind of a service is this and also if i call you, it's always busy or else my call is not sent. Please take a strict action.
