Dtdc Courier — Parcel not delivered since a month

Address:

Mumbai City, Maharashtra

I had booked a return parcel from Mumbai to Haryana via DTDC Courier wide the way bill no. M17367349 dated :-24th MArch 2015. They were unable to deliver as according to them there was no such address. I had confirmed with the opposite party and address remains the same. The courier company has not yet delivered or returned back my parcel. This return parcel was covered under 30 days return policy which has now already exceeded. I have called up DTDC several times and also emailed them several time. they have stopped replying to my emails. kindly help me with the solution to this so that DTDC pays for the loss incurred to me.
