Hello.
Hello, How can I assist you the day?
I am planning to visit a Central Park at New York due to some issues it was postponed, so can you help me with changing my existing reservation?
 Sure, I am here to serve you. Please mention your name to proceed to next step?
My name is Kenneth Miller.
Ok, please wait for a minute. I will revert to you.
Sure, I will wait.
Thank you for the patience. We did not find any reservation that matches with your name.
Not an issue. Thank you for your response.
