Amazon India — Defective item not replaced

I have ordered a Samsung M12 mobile on Feb 12 2022 and received the same on 14 Feb. But the item is found defective and initiated replacement for the same. It has been 25 days and no person has reached for collection of defective item. But status says representative approached and we are unable to meet them. Order details are attached for reference.
We have made almost 50 calls and chats with amazon customer service and still no change.
Contacted social media of Amazon an d worst response ever was recorded.
