Videocon Industries — removing channel

Yesterday, i witnessed a disappointing activity on videocon d2h, they suddenly turned off the broadcasting of ndtv india channel and the error shown was "package not subscribed". When i called to videocon d2h customer care, they activated ndtv channel, but didn't disclose the reason why they stop broadcasting ndtv channel without informing the user.

Now i want to know the reasons why you disabled the channels broadcasting?
