You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello. You are at the flight booking agency.

USER:  In the last month I have reserved a flight ticket on my name to travel to San Francisco to celebrate my father birthday but suddenly there is an examination on the same date and our college management has informed suddenly to us. So I am unable to travel the trip which I was planned. Can you please help me in cancelling my flight ticket?

ASSISTANT: Sure, I will help you. In order to find your flight reservation status about the booking which you have mention, can you please provide your name on which your previous flight reservation was done?

USER: Sure, I have reserved the ticket on the name Emily Edwards and you can check with this name.

ASSISTANT: Ok, please wait for a moment. I will check the flight reservation status and get back to you.

USER: Ok, please take your time and I will wait for your positive response.

ASSISTANT: Emily, thanks for your time and patience but I am sorry to say that I have not found your previous flight reservation on your name.

USER: I have cancelled the ticket a way before and I got a confirmation message of my ticket cancellation. As my phone got reset all the messages got deleted and I could not recognise that my ticket got cancelled or not. That's why I have approached you to recheck my ticket cancellation.

ASSISTANT: Ok, that's not a problem. As you said it has been cancelled already and I have also just checked it online and it is showing as blank that means it is been cancelled already. Is there any other help do you need from my side apart from flight ticket cancellation? As we are always happy to help our regular customers in flight ticket booking.

USER: No, that's all for now. If I need any help I will contact you in future. Thank you for spending your valuable time.

ASSISTANT: Thank you Emily. It was my pleasure to help you.

USER: You are most welcome.
