Trai — Package cannot be modified

My service provider is tata sky. Package is not getting modified and i am unable to see the channels. I am facing the problem since 12th july 2021 and i am calling to the tata sky customer care each and every day for the same issue but didnot get any resolution and tatasky doesnt seems to provide any help that is why i m trying reaching you and expect some help from your side and also my product lies in the warranty period so help me to either get the refund of the set top box as it is android box (tata sky binge+) and i am having 4 set top boxes at my house or help me for the resolution.
