Due to some issues I have to cancel my flight ticket that one of my friend met with an accident, so please cancel my flight ticket booked on my name Samantha Mitchell.
user
Sure, I will help you about that.
assistant
Thank you.

Sorry Mitchell, after checking in our database there is no active reservation under your name.
assistant
Ok, I think it might be cancelled by my brother. Anyways, thank you for your search and information.
