Blue Dart Express — missing passport

I was informed last week that i would receive my passport on 19th april. But i haven't received any call for the delivery. To add to this, when i tracked shipment on their site, it says that it has been received by 'lolith' about whom i have no idea. I am trying to reach out their customer service since then but looks like their call center department doesn't work. This is driving me nuts since this is my passport we are talking about here, and without which i will have to cancel my travel to abroad.
