DTDC Courier & Cargo — careless attitude towards customer and irresponsible behaviour towards delivery

My parents had sent a dtdc courier from chennai to me in kanpur with important documents. The same package had been sent twice from chennai following the acknowledgement from our side of not having mentioned mobile number on the envelope the first time. Having thereby included contact number and complete residential address exact, yet dtdc courier services chose to flee away this time with the money we spent by submitting false claims online in the status that i, as receiver had requested another date for delivery; while it never happened so. I did not get a single phone call from the dtdc concerned office here in kanpur regarding any issues. Pathetic service ever. Later they just sent it back by updating online that address incomplete or wrong cir. The origin place dtdc office at chennai is not much bothered to find out what exactly happened with our package, why it was returned back carelessly.
