Hi.
Hello, how can I assist you?
Owing to an emergency, my exam got postponed to future dates. So I had a request to you to change my existing reservation?
I will help you with it, Could you provide me your name to proceed further?
Sure, I had a reservation with name Sandra Edwards.
There is no reservation found with your name in our reservation list.
Ok, no worries at all.
Have a nice day.
