DTDC Courier & Cargo — Shipment not delivered, got lost

My dtdc tracking ID is D42848392, my order status is showing receiver denied service though I did not receive any call or message, it did not go back to the seller also as I called seller nd dats why he denied refund, similar incident happened to me in 2019, I lost around Rs 5000/-, now I m about to loose Rs 12000/-. This is the service being provided by private entity, nd our dearest prime Minister is so interested in privatizing everything, we common people are suffering so much, it's our hard earned money nd the private players are big fraudsters, our govt is doing nothing
