Hi.
Hello, how may I address you?
Due to some issues, I am willing to change my existing reservation. Can you please help me with this?
Sure, will you please let me know your name?
I am Larry Carter.
Ok, please allow me a minute to check the status of your formerly made reservation.
Sure.
Thanks for waiting, there is no reservation found active under your name.
That's ok, thank you.
Thank you for choosing us.
