I want to try to get help of Bharuch Blue Dart Express for to get proper advice regarding delivery of our passport, We tried for an hour on phone but no one is receiving calls, when we went their office we found that the In charge was playing game on mobile phone, i stayed there for 20 minutes, phone was contineously ringing but he ( Mr. Imran ) didn't respond the same, there was a board behind it advising customer to give his feedback, when I asked for the same book he simply gave me a blank paper, told that this is our customer complain book
