The same thing happened to me....I paid 1300/- for Chennai to Bangalore, but got a call from them at 10.00PM & they told that the bus is cancelled & they put me into a 3rd rated bus called Kallad travels which was 2 + 2 seater.... the are cheaters...
No ethics....3rd class persons.....when I asked them y the bus was cancelled...they started shouting at me in TAMIL ( WHICH I dont understand)...EOD I travelled in their alternate bus sitting in the last seat after I paid 1300/- thinking its a premium travels...
