[Resolved]  DTDC — The Parcel not yet delivered

I have sent a parcel from bangalore to payyannur(in kerala) on 5th march 2009 through DTDC courier service. The Consignment number they have given for the parcel i sent is B52152234.They told that it would reach there by 7th march 2009. I preferred the courier service to Postal is just because i wanted to reach that there before 10th march 2009. But as of now, it has not yet recieved there, and nobody exactly knows where my parcel currently is.. when i called dtdc office in kannur they are saying that its not yet dispatched from Cochin. when i called up there, they are saying that they are not sure about they have sent it or not... why these people are like this?without responsible?
