Dell India — Replaced with a faulty display and won't give me a replacement

I purchased a DELL Inspiron 5510 Laptop through Dell website on April 12, 2022. A month later, It was seen a white dot on display, and it was replaced. After the replacement, The side bezels were quite shaky and not sturdy as it should be. As it didn't bothered with my day to day usage very much, I neglected it, But the display is showing some kind of problem which they call Image Retention, It is very much affecting my usage, because it affect my privacy, as even though I close a screen, It can be still seen on the display. It all started after the replacement. I was given a faulty display, and now when I have informed them about this, They are telling me its because of my wrong usage, and it doesn't cover under warranty. I have only used the laptop after the replacement, less than a week until the issue appeared.I haven't faced anything like this on the stock display I got, which I used a month. I was given a faulty display and they are not taking any responsibility. I need the lcd to be replaced with good lcd, not a faulty one.
I am including details herewith.
