Hi.
Hello. How can I assist you?
As my leave got extended, I want to change my existing reservation. Can you help me out?
Sure, I will help you to change your reservation. May I know your name to check your previous reservation.
Sure, my name is Joseph Carter.
Sorry, there is no reservation found on your name to change your reservation.
That's fine, thank you for the information.
Welcome. Thank you for checking.
