Hello.
Hello.
My name is Charles Parker.
How may I assist you now?
I want to do some changes in my existing reservation. Can you help me for that?
Sure, I will help you.
Thank you.
Please allow me to check with your existing reservation.
Sure, I will wait for your response.
Sorry to say, there is no active reservation by your name.
That's ok, thank you for checking.
Have a nice day.
