Myntra.com — Goods are not being delivered on My Pin Code

I have been a Myntra Customer for a few years now and have been ordering from the Ecommerce site regularly, I could place the order as recent as last week, however from last 4 days I have been checking continuously and for some reason my pin code 411015 is not serviceable any more and for the products in my card I am getting a message that they don't deliver to this pin code any more.

I would like to know the reason and logic for the same and also would want them to start delivering the same as soon as possible. I am experiencing the same situation with Flipkart too, while the product is available its not deliverable at my location.
