Sun Direct — Harassment and cheating by sun direct

Address:	Chennai, Tamil Nadu
Website:	sundirect.in

I have sun direct tamil cinema plus sports package for the last 2 years and since i paid for the setup box 2 years ago, when i raised a complaint stating that some of the channels were not getting relayed, i was asked to change the setup box as if it was my fault.
I had to pay rs. 200 to get the new setup box on march 6, 2017 and also paid rs. 700 to get the channels as part of tamil cinema plus sports package. All of a sudden without prior intimation or informing me there is a tamil channel (Likewise telugu channel also) which is sun action 109 has been removed on march 16, 2017.
When i raised a complaint with customer care and nodal officer i am told that they have removed it for all customers and have been rudely answering my questions.
If i say that i will not pay rs. 700 as other customers have paid, will sun direct be able to provide me the package free of cost. I guess not and how come without keeping me as a customer sun direct can remove a channel and be able to talk so rudely.
Also, when i call the[protected] number i am being given some excuse when i wanted to talk with the supervisor stating that the supervisor will call me in 30 mins. Time and even though i have called and asked to talk with the supervisor twice i not only received any calls from the supervisor (Supposed to have received a call from mr. Harish) but also i got the same answer the second time also stating that he would call me in the next 30 mins.
Is sun direct running a charity business by cheating me in this way? How come they charged me and not provided me and rudely be able to speak to me in this way per the rti act of india.
Let me take this up legally and if i don't receive a reply by saturday i will have to take some extreme step and put the blame on sun direct including the name of mr. Harish, mr. Ajay and couple of nodal officers who spoke rudely with me over the phone stating that they have harassed me and that is the reason why i had to take up this extreme step.
