Hello.
Hello, how may I aid you today?
I am Alexander Lee. I want to change my existing reservation. Could you help me with that?
Sure, I am here to help you.
Thank you.
Please hold on, while I will check in the previous list and get back to you.
Ok.
Thank you for waiting, there is no active reservation found on your name.
That's ok, no problem. Thank you.
Thank you for approaching us, have a nice day.
