South Bengal State Transport Corporation [SBSTC] — Less quality bus

I am a regular passanger of SBSTC. I travel from Durgapur to Purulia frequently, bus timing 6.00 AM at City Centre, Durgapur. My complain is to you that is condition of the busses of this route is very bad and very uncomfortable as the journey is about 4 hrs and it would be easier to travel with a good condition of the busses. WB 39 A 3574, the seats are broken, seat no 43, 44, 45 as per I have seen. Sometimes busses are breakdown due to lack of maintenance. Hope you will understand the issue and you will provide a good solution.
