Myntra.com — product not delivered after 21 days of ordering

Myntra has not delivered by order ending with 90601 that was placed on 06 june 2019. It was expected to be delivered on 16 june 2019. I lodged a complaint on 18 june 2019, but they are only dragging saying to wait for 24 hours everyday.
Also they are not refunding the order money. I being a regular customer of myntra feel cheated at their behaviour and solution they give. They are also not looping me into the complain mail so that i can get the status. Kindly help from such fraud things.
