Flipkart — Delivered a faulty, used PS5 and refusing to return or refund

I ordered a PS5 from Flipkart that got delivered on 8th Apr, 2023. The outer packaging by Flipkart was fine but the PS5 package was already opened, it had all company seals broken already. Inside this package I also found a bill for the same product that was not in my name suggesting that it was sold to someone before and they returned it back. I confirmed the serial no on the PS5 and on the warranty card and they matched so I plugged in the PS5 and noticed that the PS5 is not accepting disks. Its disk drive is not working.

I told all of this to the FlipKart customer care several times but they refused to either return the product or replace the product.

Clearly there is a fault of Flipkart as they sent me a used piece while I paid for a brand new one. Second, the PS5 delivered is faulty so It is of no use to me. My hard earned Rs. 50000 got wasted in this scam and these folks don't seem to care at all.
