It was a complete mistake booking the ticket online with the redbud.
On reaching the bus office I had to face a lots of problems:
(1) the office adress given on the ticket was not right, I had to search for the correct office.
(2) the seat which I booked online was not given to me, I was told that only 1 seat is left which I had to accept.
(3) the actual price of the ticket was 500/- for which I paid ?900/- online.
(4) the staff behaviour was vey unfriendly.
