Delhivery — Regarding delayed delivery

Shipping date - 29 Sept 2022
It has been more than 10 days since the package has been shipped from New Delhi. I need the book very urgently. The delivery date is being shifted to the next day by the end of that day.
I also filed a complaint on their portal regarding this delivery but there has been no action till now.
I cannot understand if it has already reached Hoskote, Bangalore then what is causing such a large delay.

And to hide their incompetence, they have not provided any customer care helpline on their website. Any numbers I found on the internet didn't work.
Extremely pathetic service.

Please help to get the courier delivered as soon as possible.
