Flipkart — no update on package.

Supercomnet has received my order on 9th and yet today is 12th and still no update on the package. It is still showing order is being processed by seller while the delivery date was supposed to be 10th. Flipkart has no idea about my package and it seems apparently they don't knw anything about their own sellers. I will be leaving town but still they won't deliver my order. How do u expect customers to trust flipkart when they can't even communicate with their own god damn sellers. And why do they give a date if they ain't gonna follow it anyway.
