ASSISTANT: Hello, how may I aid you today from my end?

USER: Please cancel my recent reservation. As budget was very high for our planned trip and we are not able to arrange our budget, so can you help me with this?

ASSISTANT: Sure, I am here to help you out. Please allow me a moment.

USER: Ok.

ASSISTANT: Sorry Katherine Carter, there is no reservation on your name in our database.

USER: That's ok, thank you.

ASSISTANT: Thank you for reaching us.
