Hi.
Hello.
I am William Green.
How can I help you at this moment?
I would like to change my reservation, would it be possible to do?
I am here to help you, please wait for a minute to check the reservation details.
Sure, take your time.
Based on your request, there is no reservation with your name.
It's ok, no issues. Thanks for your information.
