I did online reservation for 4 adult seats from swargate to sambhaji nagar kolhapur
Ordinary express total fare of rs1220 (Ticket number[protected]. But the bus was cancelled and 4 seats were adjusted in semi luxury till cbs kolhapur (Not sambhaji nagar, for that i had to pay 200 for rickshaw at 1am). Base fare of semi luxury was 385*4=rs1540. I was asked to pay additional rs376. So now i paid total amount rs[protected]+376). Asking clarification on this extra charges was not answered.
Seat were arranged after waiting for 3hrs at swargate that too because all passengers started shouting at controller.
Really disappointed by the service provided by msrtc.
Hoping extra charged amount will be refunded back.
