Hello.
Hello. How may I assist you?
I am Patrick Evans. I am planning to change an existing reservation, due to health issue. Can you please change my ticket?
Sure, I can do that for you.
Thank you.
Please wait for a moment, I will check your reservation status and get back to you.
Sure, I will wait.
Evans, I have not found any reservation by your name in our database.
That's fine. Thank you for your service.
You are welcome, thank you very much for choosing us.
