Hello. How may I help you?

I would like to change my existing reservation as I got an appointment from a famous doctor for my surgery. Can you help me?

Thank you for your positive response.
user
Please be on hold for a moment to check your previous reservation in back end list and I will get back to you.

Sure, take your time.

Thank you for waiting, as per your request I have checked in our booking portal but it is showing that there is no reservation for the user name.
assistant
Oh! That's very disappointing to know form your side. Anyways, thank you for checking.
