Myntra.com — wrong product delivered & bad service

Address:

Bangalore, Karnataka

I ordered a kurtha and a wrong product got delivered to me. Then i had requested for an exchange instead they filed it as a return. Again i had to call them up & ask for an exchange, they asked me to cancel the return & ask for an exchange again. When i did so they entered a wrong address for pickup. Now they say "it has already been shipped & you cancel it only when its out for delivery and that too i have to call up the delivery guy. Then again call us up and ask for return."how is this even fair?
