ASSISTANT: Hello, how can 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 moment.

USER: Ok.

ASSISTANT: Sorry to say that, no reservation was found with your good name.

USER: That's ok, no issues.

ASSISTANT: Thank you for reaching us.
