Myntra.com — Product not yet delivered & status is shipped

I have placed an order on July 24. The expected delivery date was Aug 1. But The product is not yet delivered and the status is still shown as shipped. Many times after contacting Myntra, they have raised an issue regarding this and an executive called me and he suggested me to wait upto 14 days for an update.
It is really a bad experience from Myntra and the product can neither be refunded nor cancelled.
