National travels Redbus - Bus operator suddenly cancel the booked bus and reschedule for higher money

I had booked a bus ticket(travel date **-**-**) in redbus on **-*-** from chennai to krishnagiri. But the bus operator suddenly cancelled my ticket on *-**-** just * days before travel. Red bus refunded paid amount but when i tried to rebook the ticket the same cancelled bus operator just opened a same type of bus just * hour before the previous departure time. When i searched the price all the bus tickets where soared to double the price since the time i had booked before. So operator purposely cancel the bus and reschedule the bus in different time to earn more. But i have book ticket with double the money due to last minute.
