Hello.
Hello, how can I help you now?
I am Mark Scott.
Ok.
I am planning to change my existing reservation, due to some work. Can you please change my reservation?
Sure, I will change with that. Please wait for a while. Sorry Scott, there is no reservation found on your name.
That's fine.
Thank you for approaching us, have a nice day.
Thank you for helping me out.
You are welcome.
