Dtdc Courier — Courier not yet delievered

Address:

560100

My consignment number is V25531362 which was shipped from kolkata to bangalore, when i track the item it says it has reaches banagalore 4 days ago and out for delivery 2days ago.. I called all the numbers provided many times.. No one pocked up the phone...When my parents contacted the courier service centre in kolkata they say its delievered... Its is very disappointing companies like this do not deliver items.. The parcel is very important for me.. I want the parcel and compensation in 1business day.. If not i will take this matter higher..
