Videocon Industries — Not worth to call Customer care and technician

Hi All,
We bought Videocon Tv just its a very old and renowned company. we saw its TV from our childhood. But current experience shows 'Old is never gold, it loses its images as it grows.

last week I called customer care to repair my Videocon tv, the issue is 'Backlight issue', they didn't communicate that they will send the technician from 3rd party and the 3rd party technician will provide their own bill, not company. if something wrong happens again with my TV within the next 1-2 week, then who will take care of this. How do I know the authenticity of the technician.

The person visited my place, he wasn't good at all, after repairing my TV, the picture clarity was very bad to patches on the inside TV sheet. That I need to clean, Technician hasn't tried to clean it. thereafter I asked for the company bill, he refused to provide me. I told him to repack my TV and don't want to repair it from you. He repacked but in a very manner. Personally say, my local Tv repairer is much good than sooo called company technician.

Most important thing he destroyed my TV part as revenge. that I refused to repair my TV by him. Now my TV is totally a waste. and when I called customer care again, the lady on call started shouting at me.

Is this aftersales service provided by Videocon. Why such a big brand left their customers like this. Nobody is here to care about your product. at the time sales, the company are doing big promises and show the customer is king. But when the product goes out from the company/ showroom. nobody cares.

Seriously I am unhappy with the customer care and the service provided by leftover Videocon.
