Hi, myself Virginia Walker.
Hello, how may I aid you for the day?
I want to cancel my reservation as I have to prepare for my exam, can you please do that for me?
Ok, please wait for a moment till I check with your existing reservation.
Sure.
I am very sorry to inform you, but there is no flight reservation available by your name.
No problem, thank you very much for your help.
Thank you for consulting with our agency with your help.
