DTDC Courier & Cargo — parcel not delivered and not traceable

Address:

Kolkata, West Bengal, 700031

I sent a parcel from deepshikha orissa to kolkata on 31.3.18 through dtdc courier ref no. D42197069.in online tracking it is showing messages that 'out for delivery's and ' item not delivered' since 3.4.18. But at recipient address somebody is always there and there is no calls from courier agency so far, however phone numbers are there on parcel. I am not able to contact any dtdc customer care no. Neither any branch no. Kolkata regional office phone numbers are all the time engaged, it is very suspicious. My itel is expensive and important also very important. A strong action against dtdc poor service and unreachable contact information should be taken. Also i need immediate response regarding my parcel location as it is not traceable. It is a very disappointing service from dtdc.
Thanks and regards,
K saha
