DTDC Courier & Cargo — Not delivering the shipment with tracking id D41126908

I need to receive the shipment with tracking id D41126908 from DTDC courier service. The shipment arrived at the destination branch on 4th may but the franchise is not attempting the delivery of shipment to customer but simply updating the status out for delivery from last 7 days. Even customer care executives are very rude. They are disconnecting the calls over the face without listening the issue or concern
