How can I guide you now?

I am unable to attend a client meeting due to health issues, so I am unable to travel to my old office. Can you please help me in cancelling my  flight ticket?

Kenneth Collins, please wait for a while.

Sure, I can wait for your response.

Sorry, no flights are available for your journey.
