Myntra.com — Returning product

Address:

Bangalore, Karnataka

I had booked wiki by wildcraft unsex black and red printed bag on aug 31st or sep 1st 2016 (I don't remember the exact date)
Order no is[protected]
I had raised the request request 6 to 7 times, without any reason they are cancelling the request and i have to return the bag within 1 month of duration,
Hardly i have 5 days to return it.
Without receiving the bag, they had send a message telling product is been successfully received by delivery guy.
And how long they need to pick up the product?
Almost everyday i am calling the customer care of myntra and i registering the complain, but they are not at all takig any action regarding the complaint.
