Very worst experience I had last travel from Chennai to Bangalore. Same thing I honestly shared with red bus (they have asked for the feedback).
They have shared my details to bus drivers & lower level staffs this people started calling me shouting very bad language. They don’t know the value for the feedback. They will not take the right sprite . why the ask for feedback I really don’t know. Please not to share the feedback to RED BUS & avoid using RED BUS .
