DTDC Courier & Cargo — courier not delivered

Address:

Nellore, Andhra Pradesh, 524003

I have booked a courier from nellore to chennai on 23 july 2018 with docket no h81876403
On tracking with courier details status is shown as "in transit", when inquired with nellore office they were saying consignment reached to chennai.
Whereas when inquired with chennai office they were saying no such consignment reached to chennai.

Since 3 days i am following up with both offices and could not get exact status. The response is poor.

Chennai office contact no:[protected]
