Intex Technologies — Complain regarding to resolve TV issue

I have purchased TV on 16-july-2020, we are facing some issue in this TV, it's not working properly so, about this issue I have already raised complain to intex customer care on 30-oct-2020 then after 2-3 days intex engineer had visit and he said that TV mother board is not working and it would be changed. After 10 days they said that this TV's mother board is not available and we will send you a new TV but this TV have no complete features as in you TV.
I said, i will not accept this TV, I requested to him that give me same model TV or give me that TV which have complete features as in my TV but till the date no body resolve this issue and when we call to customer care or a person they are not resolving the issue
and it's seems they are trying to close this matter.
