I had my first experience with Redbus yesterday. Overall, it was good except for two things. First, the reporting time of the bus should be more realistic. They have asked me to reach at 9:15 PM however, bus came exactly an hour post that. Secondly, I would encourage somebody from the call centre to speak English or Malayalam, however, it seems the agent lacked both. Overall, I had good time with the bus/staff. Hope this help you.
