Hello.
Hello, how may I assist you today?
Would it be possible to change my reservation, which I have done with my name?
Sure, may I know your name for the changing process?
Yes, my name is Amy Nelson.
Sorry, as per your concern I can not amend your reservation, as your reservation is not found as per our records.
  That's ok, thank you for the response.
Welcome, thank you for reaching us.
