Hello.
Hello, how may I help you?
I want to change my existing reservation, as I am not interested to travel now. Can you please help me with this?
Ok, may I know your name please for further process?
Sure, I am Gregory Perez.
Please wait for a mean while.

Sorry Perez, there is no reservation found as per your name to change your reservation.
Ok, not an issue. Thank you for your information.
You are welcome.
