Dtdc Courier — My courier not delivered

Address:

Mumbai City, Maharashtra

My tracking no. Is m20974428, i had send courier from mumbai to banglore. It reached banglore but not its destination. The website is still showing in transit and lying in dtdc banglore office, whereas they are telling me it has reached the customer. My customer has not recevied any parcel so i complained and mailed 100 times spoke and called all possible ppl in banglore but noone is bothered. They just cooking story of reaching destination whereas when i ask for proof they dont have any copy and nor they are updating the site. Feeling totally cheated
