Myntra.com — Delivering worst quality product and denying return

I got the product in the condition it was send by you and within 30 min I requested for return and I think myntra need to check it's products before sending it to their customer because it was already used or very low quality product ...i ordered from myntra all because of great return policy but I think I was wrong because there is no reason to create a issue as I returned it in the condition it was received.they have reshipped the product and are now denying to take back even when it is their mistake. They are registering complain and then showing it resolved without even resolving it. I have been calling then daily from last 7 days which is actually very torturing.
