DTDC Courier & Cargo — A important official document

I had sent a v important document through DTDC courier from Bangalore to a Delhi location and same got delivered to some other wrong address. Facing lots of difficulties due to their negligence. I tried contacting DTDC customer care several times (Bangalore and Delhi) but no body helped and ignored my request despite of requesting them again and again. They mispresented the address by stating that "we have delivered to the address mentioned on the courier " and I kept on telling them that correct address is mentioned the courier receipt (which was given to me by the courier boy who was taking the docket from my office address)
