Trai — tatasky multitv

I have three multitv attached to my main tatasky id. As per the new dispensation i am allowed to make choice of channels i view and pay. However on each multitv different sets of channels are viewed. Tatasky app does not allow any choice of channels for multitv. For example, on one tv i watch mostly sports, movies etc but my wife on her multitv watches only hindi soap opera. She watches just 10/15 channels. I m now forced to pay for all multitv minimum of rs400/-. Multitv charges has been very unethically increased from rs240 to rs400 by tatasky. Please address this issue. Thank you
