Hello.
Hello, how may I assist you?
I made a reservation earlier in the wrong date unknowingly so, I want to change my existing reservation. Can you please help me with this?
Sure, may I know your name please?
Sure, I am Shirley Martin.
Please wait a moment I will check the reservation list.
Sure, I will wait.
Sorry Shirley Martin, there is no reservation on your name.
Ok, Thank you for your service.
Thank you.
