Hi.
Hello, how can I guide you for today?
As my exam got postponed, I want to change my existing reservation. Can you help me out?
May I know your name?
Sure, my name is William Green.
Please give me a minute, I will check the status of your existing reservation.
Ok.
Sorry, there is no reservation found under your name.
That's ok, thank you.
Thank you for contacting us, have a nice day.
