Hi.
Hello, how may I help you?
As my exam got cancelled, can you help me to cancel my recent reservation?
Sure, I  am here to help you. Can you please let me know your name for checking your ticket status?
Sure, my name is Stephanie Carter.
I am very sorry for the information, there is no reservation found with your name in our database.
That's ok, thank you for checking.
