Hello.
Hello. How can I assist you at this moment?
Due to some emergency, I am unable to catch the flight. So, I decided to cancel the ticket. Can you please do that for me?
Sure, I am happy to help you with that.
Thanks a lot for your quick response.
Can I have your good name please to check your reservation  status?
I have reserved my ticket with the name Ruth Taylor, so please check the ticket status with this.
Ok, please wait a moment.
Ok, take your time. I will be on hold.
Sorry Ruth Taylor, no reservation has found under your name to cancel.
It's ok, I think my brother had already cancelled the ticket. I will confirm with him. Thank you for checking my ticket status.
Thank you for choosing us, have a good day.
