Hi. I am Steven Johnson.
Hello, how may I aid you?
I would like to cancel my reservation, as my exam is postponed. Can you help me?
Sure, I can help you.
Ok.
Please wait for a while, I will check the reservation list and get back to you.
Sure.
Thanks for your time, there is no active reservation found in your name to cancel.
That's ok, thank you for checking.
Thank you for availing us.
