If you are ok to leave your shipment to all probabilities without any assurance or like a blind person without any chance of tracking possible date of delivery then you can go to DTDC.
In a large city like Bangalore nobody picks up any of the customer service numbers in any branch throughout the day. Most of the numbers in their website don’t work as well.
This demonstrates how scantily they consider customer service.
There is no centralized customer service for Bangalore and you have to figure out which branch your consignment will arrive at and call them.
