Hello.
Hello. How can I help you?
Due to sudden change in my exam dates I need to change my existing reservation.
Sure, I am glad to help you with that.
Thank you.
May I know your name for the further process?
I am Donna Hall.
Sorry to tell you, there is no previous reservation found under your name.
No problem. Thank you for the information.
Donna Hall, thank you for choosing our agency. Have a great day.
