Hi. I am Brenda Anderson.
Hello. How may I help you out?
I have booked a flight ticket to write an exam but the exam got postponed to other dates, so can you please help me in changing my previous ticket booking?
Sure, I will help you in changing the ticket.
Thank you for accepting my request.
Sorry, there are no reservations found.
Ok, that's fine. Thank you for checking and providing the information.
