ASSISTANT: Hello. How can I assist you now?

USER: Alexander Edwards this side, I want to cancel my recent reservation which I have done 3 months before to attend a business meeting, due to the climate that meeting has been cancelled. Can you help me with cancelling?

ASSISTANT: Sure, I will help you.

USER: Ok, thank you.

ASSISTANT: Sorry, there is no reservation found on your name.

USER: It's ok, maybe it was not done properly while booking itself. Thanks for checking.
