Hello.
Hello, how may I assist you?
Owing to an urgency, I would like to cancel my recent reservation. Can you help me with this?
Sure, I will help you in this. May I know your name please?
My previous reservation has done with the name David Brown.
Brown, please wait for a moment. Sorry Brown, there is no reservation found as per your name to cancel your reservation.
Ok, not an issue. May be something went wrong while booking the ticket. Thank you for providing information.
You are welcome and have a great day.
