Hello.
Hello, how can I oblige you today?
Due to some urgent office meeting, I am planning to change my existing reservation. Can you please help me for this?
Sure, can I know your good name?
Myself Donald Clark.
Please stand by.
Sure.
Thank you for waiting, there is no active reservation found with the given name.
Not a big deal, anyhow thank you very much for checking the reservation status.
Thank you.
