Amazon India — Replacement of defective product

I placed an order in Dec first week with Amazon for windows10 installation dvd and the seller name is Deepaksale.I Made payment through my debit card.I got a mail from Amazon that my order is cancelled.The order no is[protected].When I asked why it was cancelled, the seller said, it was cash on delivery basis.There was a call telling me that the dvd can be delivered in 48 hrs, if I accept cash on delivery basis. I accepted and it was delivered and I paid the amount through my card.I was unable to install and when I contacted the seller through Amazon, he asked me how I installed and after I explained him the problem through mail he promised to send me the replacement in a couple of days.When I kept on asking, he said he has sent it, then he said wait for sometime and suddenly he stopped responding.When I complained Amazon regarding this, they promise me to get it sorted out, at the same time they say that the seller has sent it without their knowledge, but still they will look into it.I received the item in Amazon cover, I am attaching the photographs.Now either they should give me replacement or refund.The dvd cover has the name Microsoft misspelt.Is Amazon dealing with fake products.
