Myntra.com — return issue... poor service from myntra

Address: 175018

I wanted to return the product due to poor quality issue and return for the same has been scheduled. After getting the call from ur executive i was not able to pick that day and i received a msg in the evening that it has been cancelled. After that i didn't get any call from executive... What to do? And in the app it is showing pick up will be done after 3-4days..??? Very pathetic...
