DTDC Courier & Cargo — Parcel

I have sent my parcel to pune through dtdc on 9/06/2020. But it has been more than 20 days that my party has still not received the parcel. When i called them to enquire the parcel they don't talk properly and sometimes they don't pick the call sometime full day busy... I m very tensed about the parcel that was really important for me. Now i feel that i did mistake for sending my courier through dtdc... Really a big mistake. I am not getting that where is my parcel... Your office's don't give me proper address. They always tell k hume phone krne ka koi fayda ni... Tell me that to whom i should ask about my parcel... Really very bad service. Even i paid very high charges for this parcel.
Please it's request to talk to me on this number...[protected]
