Asus India — Asus tuf a15 , display flickering issues , it has not been even a month

I recently purchased the laptop from an authorised store of the brand. It is Asus tuf a15, the laptop has display and flickering issues, it has not been even a month since I purchased. I had reported the issue to the company and the customer care as soon I noticed, but they are not replacing the laptop instead they are reparing continuously everyday saying some or the other reason without fixing. This is a serious exploitation of the customer. Asus being the renowned brand and is not giving a proper resolution and it is a huge amount of 55000.
