Srm Transports — bus service

I booked ticket from nagercoil to chennai on 11/11/2019 through redbus app
When i was board and get into seat, that was last berth. Window glass was broken and it hanging half paste.
I can't believe its very unsafe conditions
I complaint about the same to driver and others
They simply refused and they said it was happened last week. And we running same conditions no issues like.
I told them to do something and change my seat but they refused my request and we have to replace the glass once we went to main branch (Chennai).
In this conditions if any one travel in this berth they will fall down will running bus.
Very very unsafe.
