I have booked a speed post EF688863605IN on 14/03/2017 from darbhanga (Bihar) to Gurgaon. but till now my article is not delivered nor returned to me. I was regularly talking to Mr.Sunil on this no- 0124-2333020 from 20/03/2017 and provided him the exact address and contact no. but he was only telling me that your article will be delivered tomorrow. I have talked to the post man on this no 09468325273. but he was also unable to provide me the details. my first online complain was on 23 march 2017. and from that day i am regularly talking to them. i have given written complain to Suprintendent of Post office Darbhanga on 07/04/2017. then again given online public grievance portal and enquiry is still going on. Sir, I want to know how much time they will take to respond me? and will India post refund the money for the lost article? The price of my article is Rs. 6500.
