India Post — too much delayed speed post.

Address:

National Institute for Locomotor Disabilities Kolkta, Kolkata, West Bengal, 700032

I had sent my examination form for my dnb on 24th october 2019 through speed post from alambazar kolkata. The last date of examination form receipt was 30th of october 2019. I called india post multiple times and even lodged a complaint that there is no update in website regarding the tracking of the parcel. Today it is 4th of november i. E 12 days after the booking of parcel, it is out for delivery. How will the nbe accept my examination form when last date has elapsed already. I had to lodge a complaint before 30th of october about my parcel. I tried calling everybody like kolkata nsh, delhi nsh, safdurjang enclave post office and all in vain. With the late delivery of the parcel i have lost 6 months of time. And i can't write my final exam now. This is pathetic and ridiculous approach from india post.
