Flipkart delivery issue

How is it possible that the seller on Flipkart TBLOnline can deliver certain laptops in Pune near to KPA but not on others? I've been trying to get my hands on a new laptop but it's undeliverable in KPA of all places.

I've raised a complaint to Flipkart and reverted by saying that they will talk with the seller and understand the issue. How many of you have ever faced this issue and was it resolved by Flipkart that they have started delivery in the addresses which were earlier undeliverable?
