Hello.
Hello. How can I aid you?
Can you please help me in changing my existing reservation?
Sure, We are here to help you. May I know your name?
Thank you very much for quick access, myself Janet Roberts.
Give me a minute.
Sure.
  Thank you for waiting, but I am sorry to say that, there is no active reservation found with your name in our database to change it.
Not a big deal, anyhow thank you very much for checking the reservation status.
Thank you for reaching us.
