DTDC Courier & Cargo — Courier not received after 10 days

I have been told that courier will reach within 2 working days, its been 10 days over now but courier not received and no one is picking the the call.

Also nothing updated online to track the consignment.

Consignment no. B71947993

This was important document for bank and because the document not received on time so bank denied the loan and i have lost 1 lakh rupees
Which i paid to the land owner and i was suppose to get loan. But i didn't get loan so land has taken my 1 lakh rupees and went away.

This is very ridiculous service from dtdc.

I have paid 300 rupees for this but still lost the courier.
