Shiprocket — Delay in delivery of product

My product (With awb number[protected] was picked up on 24 august 2020 and it had to be delivered on 3 september. But still it has not delivered. And everyday the date extends by itself.
I am hell irritated by this company. Useless employees, they don't have any knowledge. They just gives a fake console that product will be delivered on the said date.
This is not the way to do business. I call at this company everyday but no action has been taken. They don't even take an initiative to refund neither taking any serious action.
