Flipkart — Product return rejected without any basis

I ordered a product from flipkart and received a defective product . On placing a return request for the first time, i got an email asking to share pictures of the product on a link which was inaccessible. On getting in touch with the customer care, they asked me to share it on a different e mail address, which i did but never received a response instead my return request was rejected. Again a customer care agent helped me place another request on 7th july and this time i did not even receive a mail asking for any further details and request was rejected again. I am unable to get in touch with customer care agents and even if i do, they hang up after putting me on hold for 5 minutes. Please help me resolve my issue
