 USER: Hi.

ASSISTANT: Hello.

USER: Brandon Allen here.

ASSISTANT: How may I assist you today?

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, please wait for a minute to check the reservation.

USER: Ok.

ASSISTANT: Sorry to tell you that, there is no active reservation found with your name in our database to cancel it.

USER: That's ok, thank you.

ASSISTANT: My pleasure.
