VRL Travels — Cancellation of tickets

As I have caught fever, I wanted to cancel my ticket, prior 4 hrs, I had booked ticket to Bidar from Bangalore with ticket number: TPB73744002, THESE people are not allowing me to cancel, saying you won't have option before 4 hrs, if you want to cancel before that you have to visit office, I don't think they have sense of situation, it's pendamic and they are forcing us to travel, even we are sick,
