Hello, how may I assist you?

As part of my schedule I make a reservation earlier to attend client meeting. Unfortunately meeting got delayed on week. So I want to change my existing reservation. Can you be my helping hand?
user
Sure, please wait a moment meanwhile I'll check the details of your reservation.
assistant
OK.
user
Sorry Barbara, in my database I didn't found any details regarding your reservation.
assistant
It's ok, not a problem. Thank you for your service.
