Amazon India — Refund not received even after Item returned

I have ordered Aristocrat NILE 4W EXP STROLLY 54 Bright Blue with order id Order#[protected] from Amazon India on May 2nd . I received the production in polythene cover and I see the item is torn I returned the order on 10th June in the same it was delivered. Their agent took the item but In refund status they simply mentioned package box is missing and the money is not refunded. I tried reaching multiple times to their customer care executive but no proper solution provided. I have been chasing from past 3 months for same and almost I spoke 10 to 15 times to the amazon agent but no use. They say issue will be solved in 3 days everytime but not solved till now.
