[Resolved]  Professional Courier — Missing of the Parcel

I booked a consignment with Professional Courier in Rajahmundry, Andhra Pradesh to Hyderabad on the date of 08/06/2009. The Consignment Number "RJY0469813" They told me that the parcel will delivery within 48 hours, but the parcel not reached me until yet.
The Hyderabad branch people received that parcel but they missed that parcel. I asked the Rajahmundry branch people they told me to ask in Hyderabad branch, the Hyderabad branch people gave me a letter of missing and told that they send the letter to Rajahmundry branch about the missing of parcel. The Rajahmundry people are not taking any response and the hyderbad people saying they are not taking any response about my parcel. The parcel has been lost by the Hyderabad branch people. Who will take response of my loss, and the Rajahmundry people talking very rudely and its comes to coercion. Nobody talking about my loss and behaving in irresponsibly. Shall i sue against the Professional Courier Group and if yes i will submit the attachment of Consignment Booked Slip, Missing Consignment given by Hyderbad branch.
