Hello, Cynthia Martin is my name.
Hello, how can I assist you?
Actually I made a reservation earlier to go for a trip with my friends. But due to heavy work in office, I want to change the reservation.
Sure, please wait a moment.
Ok, I will wait.
Thanks for waiting.
Fine.
Sorry, there was no reservation found on your name.
No problem, thank you.
Thank you for choosing us.
