Myntra.com — Complaint regarding Replacement

Hi, Have placed order of 2 jackets from Myntra. Both of the Jackets were of bad quality, I immediately requested for replacement for both but Myntra is denying to do so. They have rejected my request because of quality check. So it's basically a scam from Myntra, First they Shipped damaged and bad Quality products to customers and when customers are creating replacement they rejecting it due to bad quality. I request please take appropriate actions against them.
