ASSISTANT: Hello. How can I help you?

USER: I was already booked a ticket on my mother name Catherine Allen due to some office work but suddenly the office meeting got cancelled due to some issues, can you please cancel the ticket?

ASSISTANT: Sure, please wait for a while.

USER: Sure.

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

USER: Ok, no issues, I think my father might have cancelled the booking, that's why it is not showing in your data base.

ASSISTANT: Thank you  for approaching us.
