Consumer Redressal

I have sent a courier to Bangalore on 22nd March 2013, AWB No: Z84008841 through DTDC Courier. The problem was that the address to which it was sent was changed. I informed about this to all concerned persons and the franchisee. They have noted the new address but still the packet is not delivered. It is still in Bangalore (Madivala Branch) and nobody is responding from the company about the current status. Neither they are delivering it nor sending it back to me. The documents are very important and needs to be delivered urgently.
