Hi. I am Brandon Phillips.
Hello, how may I guide you?
As my exam is postponed, I want to change my existing reservation. Can you help me?
Sure, I can help you. Please wait for a while to check it.

Thank you for waiting. Sorry to say, there is no ticket found on your name when I search in our data base to modify it.
No issue, thank you for checking.
Thank you for approaching us, have a nice day.
