Hello.
Hello. How may I assist you today?
 I was fallen sick due to bad weather here in my area. So I would like to cancel my current reservation.
Sad to hear this. To cancel your reservation, may I know your name?
My name is James Lewis.
Lewis, I found your reservation and I cancelled it, because of your health issues. Anything else to help you.
No, thank you for cancelling my reservation.
Thank you for reaching us. Take care of your health.
