Myntra.com — product not delivered for more than 2 weeks and customer disconnected the call

I had ordered a top from Myntra on 19 June and they have not yet delivered it I have called 5 times in the customer care, every time they say you will get a call back within 24 hours but no call background was done.And now the last time that is the 5 the time I called the escalation team member disconnected my call.
Firstly they don't give a call back and secony when a customer calls this is how they give a resolution.
I register my complaint against Myntra service and against ms Sakshi.
