Amazon India — [protected]: 4 of kisses hersheys almond pouch, 6 x 100 g

I tried cancelling the order within few minutes of ordering it and the app showed that order is getting cancelled, however later in night i got the following email from amazon:

When delivery boy came, i was not at home and my parents received the order and now when i am trying to return it, amazon people are saying that it is non returnable and forcing the product worth rs 2856 on me.
Really not acceptable and very poor customer service from amazon.
