You are a flight assistant. 
 USER: Hi.

ASSISTANT: Hello, how may I tide over to you?

USER: I need to cancel my reservation as my friends have already booked my ticket in another flight along with them, I was not aware of this. Can you please help me with it?

ASSISTANT: Sure, I can help you with that but you will get only 85% of refund if you want to cancel. Is that okay with you?

USER: That's fine for me, you can proceed.

ASSISTANT: Ok, on what name was the reservation made?

USER: Reservation was done by the name Nicholas Evans.

ASSISTANT: Please give me a minute. I need to check the reservation list.

USER: Sure, take your time.

ASSISTANT: I have gone through the list but could not find any reservation matching your name in our data base.

USER: I think my ticket was not confirmed due to network issues.

ASSISTANT: Ok, is there any thing else I can help you with?

USER: No, I am ok. Any way, thanks for the information.

ASSISTANT: Your welcome.
