The Professional Couriers — My courier has not been delivered yet

The consignment reach the destination (Gurgaon) on 21/08/2021 and the status was "Out for Delivery". I called the courier office no body picked up the call. Till date nobody is picking up the call. I called the corporate office also, same behaviour, nobody is picking up the call. On 25/08/2021 the status is "Door Closed", which is so untrue. They haven't even tried calling the person who the courier should be delivered to noe have they called me. This is the worst experience I ever had in my life. Such pathetic service. Not sure even if this complaint is even going to take seriously by anyone because they don't know how to handle customer.
