Hi.
Hello. How may I assist you today?
I want to change an existing reservation due to sudden change in my trip. Can you help me?
Sure, may I know your name for checking with the previous reservation?
Thank you. Dennis Young here.
Please wait a moment.
Ok.
Sorry, there are no active reservations on your given name to change.
Not a big issue, anyhow thank you very much for checking the reservation status.
