DTDC Courier & Cargo — Expensive Item did not get delivered nor was returned

Address:

Kolkata, West Bengal, 700159

I send a parcel from kolkata newtown consignment num D28573684 to Bangalore in which there were some dresses n shoes n 2 cream and one very expensive lipstick. The parcel got delivered apart from the cream and lipstick and the kolkata dtdc office informed me that they would be returning the undelivered items. After not delivering it for a week, i sent someone to collect it. They still did not return the lipstick saying they would. They watsapped me saying the same and noe its been nearly a month. I have been calling at the manager's number twice a day without any effect. Is that what dtdc stands for. We send expensive items using dtdc because of its name and brand value. So disappointing behaviour. Can you please return me the item.
