If you want to interview some senior official be it from some ministry or public sector undertaking (PSU), you will die calling but you would not get positive response. The time would come when they would even stop taking your calls. There is no courtesy or consideration. If you want information, file an RTI application and wait for 30 days. Government knows slow pace of its people, that’s why prescribed 30 days for a query to be responded. Till that time news would be stale and you would be working on some other news story. There is no resolution to this problem because our country is moving at snail pace in terms of improving system and bringing relevant bills. Years pass on but bills which concern common people remain with parliament for consideration, courtesy bad dramatic politics. If you have patience, wait, else change your line. There is no better option.
