I made a booking using goibibo.com for a flight on Mumbai to Jaipur. On receiving the ticket in my email, I realized that the date is June 25th while I had intended to book for June 15th. I immediately called the customer service. The representative told me that the cancellation charges are around 3200 INR (I paid 3650 for the ticket!). That is ridiculous to say the least. Can something be done about it?
