Maybe they are updating their system of packages now, but they already updated this package from rs. 150 to 200 two or three days back.
Today, i actually activated the discounted package through website and it even sent pin code verification and activation message, but deducted rs. 300. Lol
Its still showing up here in this link along with other packages. I just checked it.

They offered it at rs 150 at 13 Feb 2016.

Then they updated it at rs. 200 from rs. 150 at 31 march 2016 (3 days ago).

And now at 3 April 2016, they are reverting it to its original rs. 300 price. Revising packages 3 times within 45 days is indeed rip off. I don't know what they are upto or maybe i am wrong.
