Hello.
Hello, what help that I can assist you?
Actually I have booked a flight ticket in the last month but now I am unable to travel due to some health issues. Can you please cancel my ticket?
Sure, I am happy to help you in ticket cancellation. Please give me a moment to check it.
Ok, take your time.
May I know your name for checking purpose?
I am Betty Martin.
No reservation is obtained in our previous ticket booking under the name that you have given for checking.
It's ok,  I think the ticket is not confirmed last time. Anyways thanks a lot for spending your time.
Thank you for approaching us, have a nice day.
