ASSISTANT: Hello.

USER: Amanda Nelson on this side.

ASSISTANT: How can I help you?

USER: As my doctor suggested me not to travel, I would like to cancel my current reservation now. Can you help me?

ASSISTANT: Sure, I can help you with that. Please let me check your reservation status first.

USER: Ok, take your time.

ASSISTANT: Nelson, I went through our database but I didn't find any active reservation under your name to do cancellation.

USER: Oh! That's very disappointing to hear from your side. Anyways, thank you for checking.

ASSISTANT: Thank you for choosing us.

USER: You are most welcome.
