DTDC Courier & Cargo — Delay in Delivery o[censored]rgent courier

Address:

560008

I have sent some medical reports to Jammu via DTDC courier consignment number V30155572 on 8th June 2016 from Bangalore.
As the reports were urgent and were required to reach the destination on Saturday I had sent them by DTDC plus service which were supposed to reach in 2 working days as told us by the DTDC courier center in Indira Nagar branch HAL 2nd stage. For this I paid INR 300 just because i wanted that courier must reach as soon as possible hence opted for express/plus service.
The courier has not reached the destination till today 14th June 21:44 pm.
I wrote a mail to DTDC regarding this but there was no reply from there side.
I called DTDC head office today 14th June and talked to complaint manager on mobile number [protected] in Bangalore and they told that consignment has reached Jammu on 11th June and talked to Jammu office keeping me in Conference. It was told that consignment has reached Nanak Nagar branch in Jammu and they promised us that it will reach today and said sorry for the delay. The complaint number which I raised with DTDC is 02376102.After promising The courier is still not delivered today.
Kindly take appropriate action.
