DTDC Courier & Cargo — Courier details show it has been delivered but I havent received the courier

Address:

India

AWB/ Tracking no: D6784279

I had ordered my books from Jaipur and they sent it to Jaunpur (Pin Code 222142)
via DTDC Courier.
The tracking no. shows that the parcel has been delivered at my address but I never got a call from anyone suggesting that the courier is being delivered. Also, no other person at my home has received it.
Since the courier contains BOOKS and I’ve to take my exams on 1st of November, I took emergency measures to even reach out the sorting officer and all the DTDC offices in & around the area, but to no avail. All the staff has been nothing but inefficient in doing their jobs.

I demand the courier to be delivered to the rightful owner i.e. Varsha Singh, at my designated address. And I need it to be delivered urgently.

This is a case of gross negligence and inefficiency to perform services. Highly disappointed with DTDC!!
