Hello.
Hello, how may I render you?
I recently reserved a ticket to visit  my best friend. But, before my journey he came to my home and gave me a surprise visit. So, now I want that ticket to be cancelled. Could you help me?
Sure, I will help you.
Thank you.
May I know your good name to check the reservation list?
I am Charles Gonzalez.
Please give me a moment.
Sure.
Thanks for waiting, but no seat is reserved for you in any flight.
Ok, no issues. Thank you for your quick response.
Thanks for your help and support.
