Great, I'm glad you're ready to cancel the booking.
To proceed, I'll need to know the booking reference number, which is SJ817-3800-123457.
Once I have the booking reference number, I'll be able to cancel the booking and provide you with a cancellation number.
Please note that cancellation charges may apply, and the amount will depend on the airline's policy and the time of cancellation. If there's any refund due, it will be processed after deducting the cancellation charges.
Are you ready to provide me with the booking reference number?
