Whirlpool India — Malfunctioning display of my Whirlpool AC

I am writing to you today to express my disappointment with the malfunctioning display of my Whirlpool ac. i have already written a mail regarding this issue but i got no response. The display on my appliance is not working properly, and it is causing a lot of inconvenience. The numbers are not visible, and it is challenging to operate the appliance. I am extremely disappointed with this product's quality, and I believe that Whirlpool should take action to resolve this issue.
and my product is under warranty purchased on 26 september 2022
