Orange Tours And Travels — Booked AC bus but shifted to non AC bus

Booked AC sleeper bus from Vijayawada to Bhubaneswar which is 14 hrs travel approximately. Immediately after 2 hrs of journey from Vijayawada AC stopped working in the bus. When intimated to driver, emergency windows were opened for air circulation and obviously its still not sufficient. Soon after opening the windows, it started raining and passengers started getting wet. After 5 hours of journey in those conditions, they shifted the passengers to another bus and far later got to know that its a non AC bus. We paid 5000+taxes for 2 tickets. But this is how we ended travelling in it. We would like to request a refund of our money and never ever want to opt this travels
