DTDC Courier & Cargo — B43528808 not delivered yet but your status wrongly shows delivered

Address:

500016

DTDC tracking number B43528808 has my important university documents.
Their website status shows this has been delivered, however, Addressee HAS NOT received it.
I try to call their Hyderabad customer care number 100s of times, but it is unanswered always.
I am extremely dissapointed with DTDC service.

Kindly check the exact location of the courier. IT HAS VERY IMPORTANT EDUCATIONAL DOCUMENTS AND I WILL BE DEVASTATED IF THEY ARE LOST!!
