Sony India — TV Still under warranty but not willing to do anything

Address:	Madurai, Tamil Nadu, 625107
Website:	www.sony.co.in

We purchased a Sony Bravia KDL-55W800C 139cm 55" Full HD 3D LED Android TV from an authorized Sony Center(THE R&R MARKETING COMPANY), Chokalingam Nagar, Madurai.
INV NO: MDU/4082
INV DATE:15/02/2016

I would like to bring this to your notice, that this TV has taken away our peace of mind.

We paid not to buy the TV, but to ruin our happiness at home. This TV is hanging very frequently. The authorized service center at Madurai has employees that do not know how to diagnose the problem. I am sick and tired of hearing the following from from every technician who comes home
(i) The WiFi should be switched off( What is the purpose of buying a smart TV)
(ii) The HDMI Port is causing problems, so use the other slot
(iii) DTH set top box should be replaced
(iv) The software should be updated and so on

This is a perfect example of the great saying" A bad carpenter blames his tools"

I kindly request you to please replace the TV for almighty's sake and give me a piece of mind

Thanks
