Hello.
Hello. How can I assist you?
I need to change my existing reservation, due to the inconvenience of travel dates. Can you please help me out in changing?
Sure, can I know your name please?
Myself Charles Young.
Ok, wait a moment please.
Sure, take your own time.
Sorry to say that, there is no reservation found on your name.
Not a big problem, anyway, thank you for the information.
Thank you for approaching us.
