Myntra.com — myntra denied taking return

Address: 400095

I had ordered a catwalk shoes few days back like one week back from myntra, i had ordered a size 39 and they delivered me wrong size 37, they denied to take it back the product saying the box is not there we want the product with the box and when the product is in the state the way i got it without any tag just with invoice.
It is really unfortunate that in spite being a known trusted fashion brand they are being so least responsible about the delivered product and disappointing the customer in many ways there where few more instances which i always ignored but this was not at all acceptable as the is really a very big trust issue factor. Because of me even my friends started shopping from myntra i was so wrong to trust these people.
From now i will not buy anything from here and i even cancelled all my further order i had placed, i will also warn everyone else too. It was my mistake to trust you guys.
But you guys should understand the fact that trust is the main factor which binds a consumer.
