Trai — tata sky fraud

As per trai regulations, consumers are allowed to select their own channels but tata sky is cheating consumers by making 100 channels as default channels and these channels cannot be removed. On adding additional channels of our choice they are increasing the network capacity fees accordingly.
I communicated with tata sky consumer service to remove fta promo channels but they replied that it cannot be removed as they are default channels. These channels include regional channels of different languages that i do not understand.
