[Resolved]  DTDC Courier & Cargo — Courier yet not delivered though it reached at destination city

Address:

Gurgaon sec15

I send courier from Gurgaon to kanpur via dtdc on 25/7/20, via docket no z30437671. It shows in tracking that it reached at kanpur, but redirected due to last mile error.
It is very urgent courier as it supposed to deliver by 31/7/20.
But still no update in tracking.
Nobody pick call from dtdc office kanpur also i called several times to dtdc customer support. All in vain as they hold my call for one hour to assign executive.
Please help, if anyone can??
