Samsung — sells refurbished and defective product - samsung book 4 i5 13th gen laptop.

I have purchased the Samsung Book 4 i5 13th Gen laptop on 12th March 2025. But the product is came with the fingerprint smudges in the screen and scratches in the charger the delivery person has got the OTP and delivery the product with that. After received the product facing series battey drain issue which not even lasts 2 hours under light use. I Raised the return request and then I called flipkart executive and explained the overall issues that I have faced while delivery & Usage of the Product. He assured that will replace or refund the laptop amount but less than 3 hours he rejected the request which I raised without any proper reason. Now they are asking me to go to service center to repair or replace the product. The product is mentioned as new but it is a defective/refurbished product and it is actually cheating the customer. So kindly take a necessary action on this matter.
