Redbus — ticket refund

Dear sir/madam

I have booked initially ac sleeper ticket from ooty to bangalore on 31 march 2018 with a ticket value of rs. 1588.95. However, due to some issues i have rescheduled the travel to 1 april 2018. However, i couldn't get a ticket on ac and i went ahead with the non-ac booking. Red bus charged me with the same charge which i was not aware off. The policy for rescheduled was not clear to the customer and neither there was no pop up at the time of rescheduling the ticket. I want the ticket to be cancelled or booked accordance with the non ac fair. Request to take refund the amount.
