Tamil Nadu State Transport Corporation [TNSTC] — bus quality - risk of life

I boarded bus from tirupati to thiruvannamalai tnstc bus. After crossedsome 50km from tirupati rain started. It was not small rain but not that much big as well. But once started raining immediately water started to ooze out from the roof of the bus. Almost all the seats were drained all the passengers including ladies, newborn babies, children of ages around 5 to 10 and old people's got out from their seat, still water came from everywhere. We even do not have place to stand all our bags and belongings were wet. How come government send such buses for the travel time of 6 to 7 hrs required atleast to complete journey. Why the driver did not stop at all. Who are all responsible for the new born babies. Action required immediately
