DTDC Courier & Cargo — Courier hasn't been delivered but status is showing as delivered

The courier sent from DTDC Coimbatore (ganapathi branch) to Erode (Aval Poondurai) branch with consignment number :C25127140 has not been received by me. No delivery has been attempted as I didn't receive any message or call from delivery person but the status is showing as delivered. All of the sudden the destination pin code has been changed by the courier service and there is no response from their end. It's very pathetic to see such a worst service from DTDC.
