Sony India — regarding thermal crack in sony bravia tv

Address:

Navsari, Gujarat, 396445

Hello
I Registered a complain to Sony center of Navsari, Gujarat dated on 3rd July, 2018.
The job sheet no is J81633415..
One Person came and examined tv and said that it is physical damage.
I Explained them that it is not physical damage because there is no crack from out side. I told them that it is thermal crack which is occurs due to Heating.
But they do not want to understand.
Please solve this issue as soon as possible.
I have attached Photos of my tv.
Please do not cheat customers by doing that.. After this issue I searched on internet and found that many times your company told this things to customer and charge them..
Do need full as soon as possible
