Hello, I am Mary White.
Hello, how may I guide you at this moment?
Can you please help me to change an existing reservation?
Sure, we are ecstatic to help you. Please wait for a couple of minutes.
Sure, I will wait.
Thanks for your time. We hardly tried to find your reservation but, no reservation has been found with your name.
Ok, That's not a problem. Thanks for your information.
Thank you for choosing us. Have a nice day.
