Sanjay — DTDC Courier not delivered still

Address: Bangalore, Karnataka

I paid for the Emergency Express Product service of DTDC of Rs, 225 to courier an emergency document from Bangalore to my homtown Kolkata within 24 hours as it was extremely urgent for me.They told me that it will be delivered within 24 hours. The document was supposed to reach by 25/04/2015 but the courier is still not delivered. My consignment no is V19286929. Please help me out in this issue . Regards, Sanjay
