DTDC Courier & Cargo — unexpected approach from dtdc with wrong updates and rude employee behavior

Address:

Kakaji, New Delhi

Respected dtdc authorities,
It is very saddening to bring to your notice that the courier which was sent from delhi (Kalkaji) to kerala (Chengannur) on behalf of amity university is sent back to the original place without any information. I received the tracking id on september 14 at 4:22 pm followed by tracking the courier, it was showing that the courier is in transit (Proof for which i am attaching with this mail). According to the dtdc tracking site the latest update was at 7:13 am on september 14. Surprisingly, in the consecutive days too i was able to see the same update. Well, i was waiting amidst this current pandemic and was anticipating it might take quite a little longer for the courier to reach me than the usual time.in between, i was constantly getting sms updates which to my surprise was showing 'in transit' till this day. By 3:35pm i received a text message stating that the courier is out for delivery followed by a text message at 3:45pm stating the same couldn't be delivered due to the wrong address. I contacted the dtdc number available on the website and a person from bangalore answered the call for the selected state kerala. He said the courier is sent back to the original place.

I contacted the chengannur dtdc and the person said we waited for 3-4 days (That should be 14th probably, the day which i received the tracking id) and my number was not available. But at the same time i received the updates in this so-called not available number. I asked him why they didn't wait for a few days and the answer i got was why didn't i contact them while i have given the delivery address too. When i raised my query along with the dtdc tracking update, he responded by saying that this was not his duty. So, can you kindly explain the duty of this "responsible person".
This was a highly confidential and valuable document from the university. Waiting for your immediate and positive response and hope you will handle the matter seriously. Please find the attached documents for the reference.
