Next day tv was delivered and reliance person came for installation.
As the box open, my wife asked that we purchased smart tv but it is normal led.
We spoke to dinesh and showroom manager they told it is better than smart and you can run all apps.
Once we insisted that told that they will ask ho for replacement.
Today they told it is not possible.
Tv has not installed as the person doesn’t know the installation process.
We request to replace with smart tv.
