Hello.
Hello, how may I aid you?
Karen Davis on this end.
Nice to meet you Karen.
I would like to change my reservation dates today, due to change in my exam schedule. Can you help me?
Sure, I will help you with the change of flight reservation.
Thank you.
I have checked with your details Karen. But I am sorry to say that there is no flight reservation on your name to change it.
Ok, that's very sad news for me. Anyways, thank you for checking with my previous booking.
Thank you.
