Hello.
Hello. How may I help you?
I have booked a flight ticket yesterday under the name of Robert Lee. Can you please cancel that ticket?
Ok, wait a moment I will check your status of reservation to cancel it.
Nice to hear that, I will wait for your response.
Thanks for your time, there is no reservation found with your name to cancel it.
That's ok, thanks for checking and for your immediate response.
Ok, thanks for consulting us.
