DTDC Courier & Cargo — consignment not delivered - customer care contacts not working / not attending

Address:

560103

I had booked a consignment from anandbagh branch (H48) [sainikpuri (Afochs) (Hf1206)], secunderabad on 14 may 2018, consignment number h08218685. The consignment was booked for bellandur, bangalore.
The tracking history shows tuesday, 15 may 18:57 hours - not delivered (Mis-route), madiwala, bangalore. There have been no updates thereafter.
My efforts to contact various customer care numbers have failed, except, [protected] (Dtdc bellandur). The person contacted says, his dtdc center has not received the item.
I wrote two emails at [protected]@dtdc.com. They have given me a case number 11404654 on 16 may 2018, but there have been no forward movements. The landlines that are given in the email do not work.
Please help to resolve this matter asap.

Best regards.
