Hello, how may I serve you at this moment?

George Lewis here. 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.

Sure, I will help you. Please wait for a while. Sorry, there is no reservation existing on your name.
