Maharashtra State Road Transport Corporation [Msrtc] — no proper information

Hello, I was waiting for a bus for Amravati from Pusad bus stop, but here not getting any proper information of i.e. When exactly bus will come. They just tell the time table & after regular time passed they got completely unable to inform that bus will come or not. They directly say "we don't know". If they don't have this information then who will guide to passengers?
