Vijay Sales — Under warranty TV back light gone and they are not responding

Address:

Vijay sales, infinity mall, andheri west.

I bought 55 inches TV from vijay sales, andheri on 13nov 2016, its under warranty for 5 years. I made the complaint and paid money to visiting engineer also.but no one is having a look this problem. My tv backlight is gone. Its been 2 months now. Please have a look at my issue. I have no faith on vijay sales now. There service sucks. I have bill details and all necessary info with me. From last 2 months, there is no tv for my home.
