booked ticket was from Kannur to Nagercoil, however was forced to change the bus twice, first at Cochin (place not sure as it was around 3 am) and other at Trivendrum at 0730 am. Change of the bus at odd hours twice made the trip uncomfortable. During the change at Trivendrum self has to shift the luggage of own without any help.
IF there is any change of bus it should be informed to passengers before the journey.
Change of bus during the odd hours should kindly be avoided as it makes passengers very much confusing and uncomfortable.
