HI.
Hello.
David Parker here.
How can I help you today?
 As I have fallen sick suddenly due to bad weather, I would like to cancel my recent reservation.
Sure, I will help you with that.
Ok.
Please wait a moment, I will check your reservation status.
Ok sure.
There is no previous reservation found on your name David Parker.
That's ok, thank you for your help.
You are welcome.
