Hello.
Hello, how may I aid you?
Please see if there is any possibility to cancel my ticket, as I will be not able to catch my flight on the date which ticket has been booked, I am going to another place on that day.
Sure, I'll check. May  I know your good name?
Sure, ticket is booked on the name Edward Gonzalez.
Ok. Give me a minute to check your reservation in our records.
No problem, I will be waiting.
Well Edwards, sorry to say this but I didn't found any reservation with your name in our records.
That's fine, I remembered now that I have asked my friend to cancel, might he have cancelled it, anyway thank you for your immediate response.
Ok. Thank you to visit our agency.
