Hello. How may I help you?

I reserved a ticket previously to meet my friend who was staying in New York but my friend was not staying in New York now, so that I want to change my reservation.
user
Sure, may I know your name please to proceed further?
assistant
Previously I reserved ticket with the name Helen Collins.
user
Please give me a minute, Helen.
assistant
Sure, please take your own time.
user
Helen, there is no record of your reservation found in our database.
assistant
That's fine, I think my brother has been cancelled that reservation.
