Hello.
Hello. How can I assist you?
Due to postponement of my examinations, I would like to change my existing reservation. Can you help me with this?
I can help you with that. May I know your name please?
My previous reservation has done with my name Ruth Green.
Sorry Green, there is no reservation found on your name.
Ok, not an issue. May be something went wrong while booking my ticket.
Thank you for choosing us.
