Hi.
Hello, how may I assist you today?
I want to cancel my recent reservation due to my health issue, so can you help me with this?
Sure, may I know your name for the cancellation process?
Sure, Debra Anderson is my name.
Sorry Anderson, we regret to inform you that there is no reservation found  for the cancellation.
Not a problem, thank you for checking.
