Hi.
Hello, how can I assist you today?
My name is Margaret Lee. My scheduled examination dates has been postponed, so I would like to change my reservation.
Wait a moment I will check it out whether your reservation existed or not.
Ok.
Sorry, there is no reservation found under your name, I think your reservation is not done properly.
No problem, thank you for checking.
You are welcome. Thank you for reaching us. Have a great day.
