Myntra.com — refund for the return

Address: #180 brindavanam pg for gents, rr nagar, kengeri, back gate near karnataka bank, Bangalore, Karnataka, 560098

I ordered one black roadster shirt from myntra which was of poor quality hence made a return request. On the day of return the delivery boy cancelled the return pickup without any concent. Next day in the morning reshedule happened, he called once and cut the phone and i received the message return failed. I called him immediately he said I am waiting outside bring your product, I gave it to him and told why i received this message. He told I will update it dont worry.
It has been days since I lodge a complain regarding this now today I got a mail from myntra that your refund has been cancelled beacuse you have not returned the product. I am having the call details for the same day. Customer care does not care about the incident, he is just saying we cant do anything. This is kind of a fraud that happened, and the man who did it knows because in our area only one man is responsible for the returns.
