[Resolved]  Tata Sky — discontinuance of mandatory doordarshan channels

It is known that it is mandatory to broadcast all doordarshan hindi as well as regional channels, but just after a month of subscription to tata sky we found out that they had stopped "DD-8"(DD saptagiri-Telugu) channel and DD-Podhgai...when asked about it the y replied that since they are adding new channels they had to drop certain channels, now i have seen only one new channel i.e.UTVi that they have added, but they claimed 5 were being added...what is the further recourse tha one might take?
