Hello, how may I aid you?

I would like to cancel my reservation due to sudden plan change in the trip, as our friends planned to go some other place this time, can you please help me by cancelling the ticket?
user
Sure, can I know your name?
assistant
My name is William Thompson.

I'm sorry William, there are no reservations with your name.

Ok, no issues. Thank you.

Thank you, have a good day.
