Hello.
Hello, how best may I serve you today?
As my meeting got postponed with my client, can you please help me in cancelling my existing reservation?
Sure, I am here to help you with that, can I know your good name to proceed further?
David Hill here.
 I am very sorry to inform you that there is no reservation found under your name in our database.
That's ok, thank you for checking.
Thank you for choosing us.
