St Courier — Product couriered was delivered

Refer AWB no. [protected] booked on 08/11/23 from North usman road chennai. It was supposed to be delivered on 09/11/2023 at Mangadu, chennai.
As of 11/11/2023 8.00 pm still not delivered.
Pathetic. No response from courier.
Worst service by ST COURIER.
I notice that they should be paying GST also.
But notmentioned in bill.
