Sony India — Sony India sony kdl 43w800d main board problem

Address:

Yavatmal, Maharashtra, India

My Sony bravia kdl 43w800d suddenly stopped working. I logged a complaint with request ID 70306476. Next day technician went to my home and checked the tv and said tv need to take to service centre to check the issue. After two days, I received a call from technician Montu([protected]) saying “main board of tv is not working and need to replace and since your tv model is discontinued from the service, I have to close the ticket and repair your main board offline which will coast Rs. 10000.” When I denied to pay that much amount technical delivered my tv unrepaired.
What kind of service is this from Sony…!!!
I feeling guilty of myself that I bought Sony tv. No common man can afford this much service cost (replacement of main board).
Please help to resolve my query.
