http://track-chinapost.com/start_indiapost.php shows the last location was in Beijing on Aug 12. You should wait about 4 to 6 weeks after that date.

@jyotibawa - There is no other way to track the package once it leaves china, except what i had mentioned in another thread on similar query. (copy pasted it below)

All you can do is, ask the seller to extend the buyer protection by few more days/weeks and then you can try and contact the Kolkata customs office/head post office for your package's status.

As a last resort, open dispute at the seller's site (aliexpress for example) for non-arrival of package in 35 days time (or whatever the shipment delivery time schedule shown by the seller).

@mebaali - have you ever tried contacting Kolkata customos / head office for your pending posts.. Do they actually have time for us and reply?
