Amazon India — Return and refund related issue.

I purchased a product from Amazon on June 3, 2017 (order Number[protected]. Due to size related issue I tried to return the request on June 10, 2017.They send me a message that they will pick up the product from my address. After so many days (after connected with customer helpline several times) they told me to cancel the return request and apply for again to initiate the process. As per the discussion with them I again apply for pick up return. They have also provide me a Return Instruction but as they did not picked up my product I again called them. One of the representative told me that my product never be picked up however they documented that they will pick up my product.
