Most third grade travel company. They are cheaters. I booked a ticket from Chennai to Bangalore for this travels via Abhirami Travels in Chennai by paying a premium fare of Rs 850. Middle of the night they made me get down from the bus in Koyembedu and put me in some other third grade bus.
These are cheaters be careful. DO NOT TRUST THEM. They have no ethics and will sell your booked tickets if they get a passenger who is willing to pay more.
