Hello.
Hello, how may I assist you today?
I want to change existing reservation due to postpone of my exams. Can you help me in that?
Sure, may I know your name for the changing process?
Joshua Robinson here.
Sorry, as per your concern I can not amend your reservation, as your reservation is not found as per our records.
Ok, no problem. Thank you for checking.
