ASSISTANT: Hello. What can I do for you?

USER: I recently booked a ticket to visit my uncle's house, but, unfortunately that place has been covered with terrorists. So, I want to cancel by ticket. Can you help in that?

ASSISTANT: Sure, please wait for a minute. May I know your name to proceed further?

USER: My name is Shirley Rodriguez.

ASSISTANT: Sorry Shirley, I cannot find any reservation with your name. Is there anything else I can do for you?

USER: Ok, thank you for you information.

ASSISTANT: It's my pleasure.
