Hyundai - Poor quality and defective machine sold

I purchased Hyundai washing machine and within * month of usage, the spinner top lid for damaged. Basically the pin connecting the sides of lid is very poor quality resulting into damage. We are family of * and the spin lid of the machine is very rarely used in my home, since we prefer getting the clothes dried manually/ naturally. Since it's the company's fault for manufacturing defective and cheap product, I want the company to get my machine repaired without any cost. My machine is still under warranty
