VRL Travels — cockroaches in the bus

Traveling from mumbai to belgaum i shift multi axle volvo ac sleeper bus
Paid 1680 for the ticket and on boarding the bus and reaching the seat saw multiple cockroaches on the seat, curtain and rods
This was not just on my seat but all the seats in the bus... All the passengers were troubled by it
Couldn’t sleep one wink because of them
What is the point of paying so much for the ticket when the quality and hygiene in the bus is zero?
