Hello.
Hello, how can I help you?
 I want to cancel my reservation which is done recently, due to business meeting was postponed. Can you help me?
May I know your name please?
Sure, I am Jonathan Martinez here.
Sorry to say, there is no reservation on your name in our database.
Ok, It might be canceled by my brother, but he didn't inform me.
Thank you for opting us. Have a nice day.
