India Post — parcel undelivered, poor postal service

Address: Kamrup Metropolitan, Assam

I'm very tensed due to the lack of expected postal service. I have posted a parcel via 'speed post' on 25th july, 2017. However the same have not been delivered to its destination yet. It's 5th of aug today. I've tracked the parcel, it been showing in aurangabad (Maharashtra) since 27th of july, which instead should be delivered at jayanagar (Bihar).

Who will bear the liability? It was an urgent delivery and i'm not ready to bear any of the losses. Please rectify my error by sending the delivery by 7th of aug, or i should be compensated for all my losses. Please look into this matter as soon as possible.
