Indian Postal Service - Speed Post — Shipment delayed/No status update

Address:

Hyderabad, Andhra Pradesh

I sent a package to Chicago, USA with clothes from Hyderabad, Patny center post office through speed post on 20/06/2011 and the tracking # EN[protected]IN.
Status still shows that the package with Origin Post for packaging at Mumbai dated 23/06/2011 and no information on further shipment details.
Can anybody help me how to track my shipment and get this delivered to my destination in Chicago, USA.
I don't understand how come speed post packages moving as a slow snail.
