However, i am not able to view most of the news channels like NDTV, CNN-IBM & regional channels like Asianet, surya etc. for the past 1 week. I have also called the toll free no. of [protected] for registering the complaint from past week & i got reply that a technician will be coming to attend the problem. However till date no technician has come to attend the problem.
