Maharashtra State Road Transport Corporation [Msrtc] — I am complaining about seat booking

I have booked 2 seats for the Swargate-Miraj "Shivashahi" bus of 23.00 on 13/12/2019 through the app. I was with a lady. We were travelling to Islampur. We came to the bus stand a little bit late. But till, our seats were allotted to other passengers by Swargate Conductor. We have travelled the full journey sitting on the floor of the bus. We want justice for such action taken by MSRTC.
The behavior of the bus driver was very rude. He was refusing to aboard us.
We were in trouble that night. None was helping us. Even though we had booked our seats earlier, we have traveled whole journey in standing or sitting on the floor. The conductor and driver had shameful and irresponsible behavior.
I am condemning such an act. We want justice.
