Myntra.com — wrong used product delivered and denying to take return

Address: Hyderabad, Telangana, 500032

Website: myntra.com

I ordered an Alcis women navy blue solid running tights from Myntra. When the delivery is successfully completed, I find wrong and used product being delivered. I place a return request for the same but later when the delivery person arrives he denies to take back the product. I do not understand if this issue is happening to all my recent orders where I have to call customer care multiple times to report issues but still the issue is not resolve.
Similarly i have issues regarding refund also.
