DTDC Courier & Cargo — My package is not delivered. Which was sent 19 days ago and after multiple complaints online and customer care

My package was sent from Rohtak Haryana on 12th Feb 2021. And today 3rd march 2021 my package is not delivered yet. This package is in Bangalore from last 15 days and the delivery location is Bangalore also buy i am surprised that they were not able to deliver in such a log duration also within Bangalore.

I have made several request online but no solution yet not even a call back yet.

You can say that DTDC has Worst Customer care center. Was told more than 10 times that my shipment will be delivered next day which didn't happen.
Was told that they will check and will call me back several times . But never happen even once.

I have food supplements in that package and now i am worried where and how my package is kept they might spoil out there.

I am feeling cheated and frustrated now. Seems i can`t do anything other than stop using DTDC services.
