Delivery Courier — product is not delivered after 18 days also through delhivery couriers

Address:

Hyderabad, Telangana, 500072

I had ordered a refrigerator on jan 27th 2020 but the product is not yet delivered, courier partner is delhivery courier.
The executives/delivery boys of delhivery courier are irresponsible, it's a very worst experience with delhivery couriers.

The shipment is mis-routed 2 times and the delivery boys are not calling to customer number, i had visited delhivery courier place which is in bharat nagar, panduranga nagar, near avanthi nagar erragadda hyderabad -500018
They are saying we are not aware of this tracking and we are not responsible.
I had called to shamshabad delhivery courier number and they are also not responding.
The product is routing between shamshabad delhivery hub and alwal delhivery hub.

I haven't seen such a worst delivery courier like delhivery company, don't know why the salaries are still paying to delivery boys.
