Myntra.com — Not accepting return of wrong product delivered

I had ordered a da milano wallet from myntra with order id- IN[protected] delivered on[protected].but a wrong product was delivered .
On complaining for return they are not accepting the return.
I don't know whose fault it is, Da milano or myntra but i am suffering .
I have been calling customer care people daily for the past 6 days.
Now that the return period of 7 days is getting over, then you would say time for return is over, are myntra people doing this purposely.

This seems to be cheating on your customers . I am uploading the pictures of the product delivered.
kindly revert back.

thanks
