DTDC Courier & Cargo — Product not delivered

I have sent one parcel on dated 18/06/02020 from ranchi to new delhi (Pin-110019) consignment no-v58905919, it is not delivered yet and show current status on dated 22/06/2020 "office closed or door lock - (Cir)" in tracking site. Banks are not closed in office hours but before and after office hours it remains closed. I have also given two contact numbers but dtdc not contacted. Now they returning the same without trying three attempts. Very important official documents are in parcel which required to be delivered urgently. It is very irresponsible behaviour of dtdc.
