Punbus / Punjab Roadways — Unresponsive behavior of bus conductor

My mom, me and my brother have to travel from ludhiana to sirhind and further change our route and traveling time was just 2-3 hrs but had to travel 5-6 hrs and also my mom can't travel by bus . We have to go ludhiana to sirhind but by mistake we get into route bus ludhiana to sangrur, we were unaware of route . I asked conductor 2 times that will bus go to sirhind, he replied yes but when the bus was about to reach malerkotla, I asked again will bus, go to sirhind then he replied no this, is, not our route .so we have to travel back malerkotla to sirhind in private bus and we were out of cash and arranged money at a time and reach our destination 11: 30 am and left ludhiana 6: 15 am .
I want my money refunded as soon as possible and reassurance that nothing such will happen with any body in future .
