Hi.
Hello, how may I help you better today?
Earlier I made a reservation for my trip through an agent but, agent booked on wrong date. So, I request you to please change it to my actual date.
Sure, I can help you to change your reservation.
Thank you for considering my request.
Please may I know your name to find your reservation?
Sure, I am Debra Wright.
Sorry, we did not find any reservation on your name to change.
Ok, no problem.
Thanks for reaching us, have a nice day.
