Sony India — I need a new TV as this is proven defective

Address:

701 GPRS IMPERIA HOMES, SHIVAJI NAGAR, NEXT TO SONA HOSPITAL, VAKOLA, SANTACRUZ EAST,

I had purchased this on 12th oct 2019. It was installed in november and i shifted to this new home in january. The tv stopped working and a complaint was made to sony care and kohinoor. Due to the lockdown the complaint has not been attended. A few days back the sony technician visited and said the motherboard is not functioning. I told him i don't want to repair. I need a new piece as this is proven defective.
