Sorry to say, but it was very bad experience of trip from Ongole to Chennai. I booked ticket for A/C sleeper and at last I came to know about the cancellation of sleeper bus. It was compulsory for me to go to Chennai, hence I went with semi-sleeper, I was told to sit in the last seat. It was very painful experience. I paid for A/C sleeper, I request you to take the amount for semi-sleeper and pay me back the remaining amount.
