Hello. Myself Edward Martin.
Hello, How may I aid you?
Actually I made a earlier reservation to go for a trip with my friends, but heavy work load in office I want to change my reservation. Will you help me with that?
Sure, we are glad to help you.
Thank you for accepting my request.
Please wait a minute.
Ok, I will wait for your response.
Thanks for waiting, there is no active reservation on your name to change.
Ok, not an issue. Thank you for your information.
Thank you for availing us.
