Kallada claims to be the largest travel operator of South India, but its monopoly. I waited in the stop for three hours from 10.30PM till 1.30AM. Called more than six times and kept confirming that the bus is arriving, but finally, I found out that the bus left already without even stopping in the pick up point.
The reason driver says is "Your phone was switched off". Made the calls to them from the same phone.
Finally, I had no other choice except coming and going to bed.
If operators like KPN develops well in this route, Kallada will be nowhere.
