Hello. I'm Mark Jones.
Hello Jones, how can I help you today?
My business meeting has been postponed. So, I would like to change my existing reservation which is under my name. Can you please help me with that?
Sure, I can help you with that.
Thank you.
Sorry to inform you, there is no reservation found with your name to change.
Ok, no problem. Thank you for checking. Have a great day.
Thank you.
