The preceding statement clearly said there are no returns and refunds. How did you decide that the product can be returned? Was that written in invisible ink that only you could see?There you go. You know there is nothing wrong with what they have done and you have just said it yourself.
You have said that an ipad Air is defective because it comes with 9 GPU cores instead of the advertised 10 GPU cores. If an Apple product is defective, you can return it. Therefore you COULD return it. However, we know it’s NOT actually defective, and as you said you cannot return it under Indian Law.
That should tell you something. The iPad Air is not defective and comes exactly as promised. OR you would be able to return it. Thanks for clarifying your position as you knowing they are right, and arguing against yourself for so long.
