Sony India — No resolution

I bought a TV in 2018 for more than a lakh and now the TV is not working and have been told multiple times multiple issues and then finally was told panel issue and they don't have replacement panel available for the same. So they offered me another TV for discounted price of 70k in exchange of my TV. But exchange offered TV is available elsewhere at almost the same price. I have tried to reach Sony in so many possible ways but they don't respond. I don't want a new TV that price is not affordable and justified considering my existing TV is just 4 years old, please just fix my TV. Can't escalate and it's in service center. Brought with lot of trust but extremely disappointed
