DTDC Courier — Poor service, irresponsible behavior even after paid for express delivary

Address:

Kota, Rajasthan, 324007

I booked my courier no V26039392 on 12/11/2015 and paid for express delivery from bangalore to KOTA, rajasthan but till 15/11/2015 i didn't get my package whether i have written that these documents must reach within time as consist exam forms, but they hardly care about it, i even send mail to regarding offices on mentioned mail ids in tracking but didnt get any reply. i tracked their contact no and try to call the concern office in kota on 15/11/2015, morning 11 am, . After so many try they pick the call and said that they will deliver it today. i took the no of delivery boy to track it but that person didn't even reply. after continuous try he picked call at 4.30 pm, and said that he will deliver it after 7 pm.As it was important for me not for DTDC so i sent my father at delivery boy location and collected the courier. If DTDC doesn't concern and responsible for time line delivery and don't care about the importance of consignment then why they make false commitments, even they ask to pay more and we do but not concern for that. its very disappointing.
