Travelled by 1115 pm sleeper bus number PY01CB9919 Chennai-Bangalore. Reached Hosur at 430am and the bus did not move till 700am. The driver said they dont have permit and we have to change into another bus. They did not bother to keep a bus in waiting and some bus crossed our bus went to Bangalore and it came back to pick up us. No business can sustain if they think can do what they want. These guys should come to street as beggars. Knowing very well KPN is the worst among the options, had to do this on emergency and it was a bloody experience. I know that they will give a damn to these complaints, but I want other users to know.
