Trackon Couriers — shipment undelivered and no response from the courier team

Hello,
Our shipment with cosignment no:[protected] is not delivered. But in your website it is showing as delivered. It is our company delivery address and we put seal and signature every time.

But your local customer service delivery hub people are very rude and unprofessional and they are not providing any update about the couriers.

We had reached to trichy hub contact number [protected] several times and they are not updating about the status. They simply state they could have made error. So what is the status of the shipment?
