You are a flight assistant. 
 USER: Hi, myself Daniel Rodriguez.

ASSISTANT: Hello Daniel, which service you are expecting from my side?

USER: I'm looking for cancellation service, will you provide that?

ASSISTANT: Yes, we do.

USER: Last week I have booked a ticket to Boston. But, due to some health issues my doctor prescribed me not to do journeys for a month. So I want your help in cancelling my reservation.

ASSISTANT: Sad to hear this Daniel, Sure, I will help you in cancelling, wait for a moment please, to check your reservation status.

USER: Sure, take your own time. I will be online.

ASSISTANT: But Daniel, I did not find any reservation with your name.

USER: Oh! That's ok, may be I have done a wrong booking. I will check it once and get back to you later. Thank you anyways.

ASSISTANT: My pleasure Daniel. Take care of your health.

USER: Sure, thank you.
