Amazon - Package not being picked by return team because of verification required by Amazon

I started return process for my laptop which was sold to me by Appario Retail Private Ltd on Jan ** at **:** PM since the laptop that I received was defective and the display did not not work for the laptop. I googled about that issue and I came to know that a few others have faced similar issue with Asus branded laptops.
The customer service was a huge pain in the butt since they were not willing to start the return for the laptop until the issue was approved by their expert technician, for which they couldn't allot me a slot. The reason I bought this laptop was to aid myself with my exams and so I was disappointed at my decision of purchasing the laptop online via a brand I used to trust - Amazon India.
Finally, after sending the customer service various pictures of my laptop and it's serial number, I was told that a return agent would be visiting my place on Jan ** between * am and * pm. They did visit that day but they told me that they won't be able to pick my laptop up because my display doesn't turn on, and hence the verification failed due to which they are not able to accept my return. I called amazon again and they apologized for the issue and told me that they will be starting another return where no verification would be required for picking my product back up. And they gave me a slot for **st Jan, **** between * am and * pm once again. I called the return pickup agent once again and they told me that they still were facing the same issue and that I should visit their office so that I could explain my problem face to face to them since if they pick this shipment up and Amazon rejects the return, they are the ones who would have to pay the amount. I called amazon again and they told me that the pickup return service was not right and that the request this time indeed did not ask for verification. But well, I visited them around * pm and they explained me the procedure, which made me conclude that someone at Amazon did not do their job well. So I called Amazon again from the pickup courier's office and the lady who I was speaking to basically told me that it was my fault and I shouldn't have done this and that. My return window expires today since today marks * days after I received the product, thanks to their new * days replacement policy. That lady was quite rude to me and she hung up the call on me without giving me her name or employee id number. I then called Amazon once again and they told me that this time they will also be issuing a NOC which should help them pick my item back tomorrow - on *st Feb, ****. But I thought of making this complaint online anyway since I am not happy with the way I was treated by Amazon and for all this mishap. And this should also act as a warning for everyone else who are thinking to buy expensive stuff from amazon, which I strongly advise against. Appario is supposed to be one of the best Amazon fulfilled sellers and they sell defective laptops. Amazon is supposed to be one of the best customer eccentric companies out there but all they've been to me is a big pain since they won't want to refund my money until the laptop is received at their warehouse which would take it's own time and until then, I would have to rely on my other laptop which is not in a reliable state and can make me cost my exams
