The AC was not working for the first 3 hours - It was hot and stuffy in the bus. We tried telling the staff, but they responded that the AC doesnt work in the city, and once we go out, it will start working. When we saw the AC Controls, the temp showed 30deg. They were not aware of how to operate the AC controls and kept fighting with us saying that the AC was on. Only the blower was on and they were unable to tell the difference. Finally another passenger operated the controls and fixed the issue.
