Hi.
Hello, How can I assist you?
Due to the sudden change in climate, my FIFA tournament rescheduled to future dates. So I had a request to you to change my existing reservation?
Sure, May I know your name?
Yes, I had  a recent reservation with name Stephanie Clark.
Please wait a moment.
Sure.
Sorry, No reservation found on your name.
Ok, no worries at all. Thanks for your kind service.
Thanks for reaching us.
