Myntra.com — made a return request on 4th august, but still no one came for pickup

I made a return request on Aug 04 2017 and I got msg that they accepted my request and expect to pickup on or before 07 Aug. Return no.[protected]. The most trouble they create for me that they don't accept email directly now, in response they telling me to contact them directly from all through 'Contact us' but there are no option to e-mailing but a customer care number but also that is not toll free. I never experience such trouble with myntra before, really very disappointed.
