Yonex Co Ltd Japan — Broken string and screched farme of badminton racket

I have bought nanorat light 18i badminton racket from amazon on 30th march of 2022.
Since then i have used this racket only 3 to 4 time.
And the string is already broken from top of the frame...and frame is also screched from the top of frame.
It cost me around 1900 Rs/-.
As yonex provide one year warranty on it's every product.
I want replacement of my damged racket.
