DTDC — Not got my courier back after it came back

Address:

Pune, Maharashtra

My courier came back via dtdc as it could not be delivered due to some reasons and they took almost 5 days for getting it back. The representatives are also not very helpful and they are misguiding. I have done the courier on 6 jan 2015. and also while getting it back they are telling pay more money (Rs 250) and they will send my courier in one day to the same address on which they have not delivered previously.
