while coming back from thiruchendur to bangalore, i choose KPN travels.THIS IS A SLEEPER COACH. the bus started at the right time, but reached one hour late. not only that. There is no proper place to sit even if we go 10 mins earlier. the staff of KPN travels behave worst than govt bus staffs. the light switched does not work. No charger points. Being A/C vehicle, the window sliders will keep on opening.
