Myntra.com — shipping charges applied in free shipping order and sent two shipping invoices

Address: G.D.colony, A-313, third floor, mayur vihar phase 3, New Delhi, Delhi, 110096

I placed an order when there was a free shipoing order and myntra applied a shipping if rs.149 saying that there was no such offer. I sent them the screenshot of the order where it clearly said that there is no shipping charge but they did not agree and not ready to listen.

It's not for the first time, i earlier complaint about a fake product and they did not accept it that time also and later took it back.
