Very bad experience.As we boarded bus, after 30 mins of departure driver ceized AC, as bus is enclosed and all passengers where not aware about Ac shutdown feel suffocation.On complain extra smart cleaner answer that one of the window might kept open and thats the reason its hot, I personally checked and confirmed that all windows wher close. When I checked the dashbord AC indicator, it was on blower only.He repeated same as many times during the whole passage and at midnight driver has shut down the whole AC and blower. At 0530 hrs I again checkd the indicator and it was shut.Again at 0630 driver shut AC and I called head office for the same. I really don't understand if I purchased AC TICKET why the held this illiterate people dont use, or they want less diesel consumption. I request please dont use devkrupa bus service.If any one need proff I have the picture of AC INDICATOR anc bus number.
