Hello, How can I aid you?

Usually I prefer a connecting flight, but unfortunately my friend has already reserved my ticket with a direct flight. So, I want to change it. Can you help me with it?
user
Sure. Wait for a while.
assistant
OK.
user
Thanks for waiting. There is no reservation found on your name.
assistant
No problem, thank you.
user
Thank you.
