Hello.
Hello. How may I help you?
Can you help me to change my reservation which I had done recently?
Sure.
Ok, thank you.
May I know your name please?
Ok, please check for the name Matthew Walker.
Please wait.
Sure.
Thanks for waiting. But I am sorry to say that there is no flight reservation on your name to change it.
That is ok, may be my friend had changed the reservation for me and forgot to inform.
Thank you.
