Hathway Cable & Datacom — Poor service, channels promised not provided

Address:

Hyderabad, Andhra Pradesh, 500016

Our building has been monopolised by Hathway for cable connection and I have been using it for about 10 years now. However, since last year, the quality of service has totally gone to the dogs. They have hiked up the price twice in one year. We pay for the service, but most of the channels don't play smoothly - the channels keep scrambling, with a lot of noise, voice and video lags and constantly goes off air with the Technical Problem message coming up.
Since last Saturday (May 20) I have been seeing the Technical Error message on most channels. I complained to the contact person on May 22, he came and checked on May 24th and said only I seem to be having the problem. He promised to come in two days time to rectify the issue. It's been 4 days now but there is no response from Hathway. The problem continues but there is no effort from their side to resolve the problem. I am tired of putting up with such poor service. We consumers are taken for granted in India. It is only here that cable companies and mobile operators can get away with poor service and we end up paying up and still not getting proper service. There should be some new rule where we will get discounts when they fail to provide accurate service. When they are at the receiving end hopefully they will improve the quality of their service.
When I refuse to pay the full amount the following month because of these repeated problems, I am told that I will have to make full payment even if service provided is not up to the mark. Channels like Sony are not coming at all although it is part of the Rs.250 package.
I am a working parent and am not at home all the time, so I do not want to spend a lot of money per month for cable TV when I hardly watch a lot of TV. Otherwise. I would have opted for the other dish TV options which are more expensive.
What action can be taken against Hathway Cable TV Hyderabad for the shabby service they give? Please guide me so that I can take action accordingly.
I have attached a video of Zee channel on which the movie Dangal is playing now. You can see how bad the relay is.
