DTDC Courier & Cargo — I am complaining about non receipt of my package

The tracking no. D81903519 was shipped from Delhi on 10th Sep 2021 and today is 18th Sep 2021 and I have not heard back of my package. Upon calling to the local DTDC recipient each one of them giving a new number to contact and no one is confirming where my package is. I have tried calling the customer service no. [protected] but after half an hour of wait time the call got disconnected. Pathetic service by DTDC I ever had. This is the type of customer service you people are providing. I will post this on all social media as well. Very very very pathetic customer service.
