Videocon Industries — videocon led tv problem

Address:

Thane, Maharashtra, 400603

My tv stopped working before its warrenty period. So i raised complaints. Technician arrived and told me that 2 parts needs to get change. So he ordered those parts and asked us to wait till they arrive. It's been 4 months now. I am television-less. No one is picking up my calls. Call centers are not taking any accountability. Tekcare india pvt ltd handle everything on behalf of videocon. Their escalation team is also not responding to my calls/messages. Help
