Amazon India — Received old broken laptop in place of ordered Dell laptop, No refund or return pick up from Amazon

On 15th of July on amazon prime day sale I ordered a dell laptop model- Dell 14, Intel 12th Gen i5-1235U and received a old broken ibm thinkpad in place of it. Raised this issue with amazon and they assured that they will carry on investigation and the refund is only possible after return. Every time amazon is raising a pick up request and every time the pick up is getting cancelled by the pick up person. As a reason of pickup cancellation amazon is stating pick up is denied from my end which is a lie. Once an amazon representative sent mail for refund too due to multiple time pick up failure but amazon did not initiate any refund and again put me to the same cycle of raising pickup request and cancelling pick up.
