Tata Sky — charge of rs. 23 for seeing republic tv (channel number 616) which is free channel

I had complained about tata sky cheating customer by charging rs. 23 per month for seeing “republic tv” a free channel by not allowing customer to choose this channel in the free channels group of first 125 channels.
Tata sky informs the rules that charge for first group of 100 channels is rs. 153 and each additional channels of 25 free channels rs. 23 additional will be charged.
Agreed. But the cheating is that customer is not allowed to choose which channel is included in the group of first 125 channels. Tata sky decides the channels which are included in the group of 125 channels. Customer can not choose them.
Why i am not allowed to choose which channel i want to include in these 125 channels?
Why i am not allowed to add republic tv channel within the 125 channels, so that i do not have to pay additional rs. 23 for next group of 25 channels.
Tata sky forces me for first 125 channels of their choice and not allowing me to choose which i want to include in first 125 channels which are forced on me.
I don’t want to see those channels, i should be allowed to choose republic tv channel within the group of 125 channels by removing other unwanted channels forced on me.
Will you respond to that?
The principal of “pay only for the channels you see” is not followed by forcing unwanted channels in first 125 channels. Why customer has no option to choose which channel customer wants to include in first free channels?
