Van Heusen — Pant got faded and torn out just in 9 Months with very limited usage

I have bought a Costly blue jeans of worth 3300 on July 23 2022. I am working in IT sector where I hardly go to office once a week. Its just 9 months not even a year, my pant was faded and torn that I cant use it anymore. I didn't expected this type of very poor quality material from an international renowned brand. Previously I have bought other brand jeans like basics, Cherokee etc... where I used those pants for about 4-5 years with regular office visits at that time. Please note that this is not only one cloth I use daily... I have other lot of clothes. Very disappointed by the poor quality products from them. I strongly urge for a solution.
