DTDC Courier & Cargo — product not delivered deliberately

Address:

DTDC WARNAGAL- MANIKONDA (PIN:506003), 506003

I have send 51 grams of important documents through dtdc express
Services from silchar, assam (16/10/2019) to warangal telangana which costed me a hefty 335 rupees. On 21st my dad (Recipient) got a phone call saying my package is out for delivery.
He asked for address and after my dad patiently told him the address then he
Peevishly says that we don't have boys here right now, we will deliver it tomorrow.
After that incident, my dad was desperately tried to contact him, through his contact number, but he didn't answer approximately 30 calls from my dad.
Then even after 2 days the courier was not delivered, and i have received and e-mail saying the package was delivered to ('fah hi kak").

I mean"what's this?".

I lost my scholarship amount due to the delay of this documents.
When i was tracking my documents i noticed that the courier transferred like this:
17/10/19 : shipped from silchar to guwahati.
18/10/19 : shipped from guwahati to hyderabad.
19/10/19 : reached hyderabad facilty
21/10/19 : reached warangal (Out for delivery).

I paid a huge amount for these papers so it can reach the destination one or
Two days earlier than indian postal services and i also believed that tracking was easy.

The package took one day to travel from guwahaiti to hyderabad
2400 kms and took two days to reach for warangal (175 kms).
It can be clearly seen that the package was not regarded as an express service, it makes me wonder weather i paid the amount for nothing. What's my package was doing in 2 days at hyderabad itself.

I want my package to be delivered to where its supposed to be and i want that warangal (Pin : 506003) office facility to respond to my father calls and answer for what they did to.

I want serious action on the guys, responsible for the delay of my valuable documents and wrong delivery. It is clear that they spoofed the delivery saying delivered to"fah hi kak".

If there are any lawyers, please tell me weather i can sue them for my losses.
