Hello. How can I assist you at this moment?
I want to do some changes in my existing reservation, can you help me for that?
Sure, I am gleeful to help you with that. May I know your name please?
My name is Michael White.
Please wait for a while, let me check your previous reservation status.

Thank you for waiting, but I am sorry to tell you that, there is no active reservation found with your name in our reservation list to change it.
That's ok, thank you for checking.
