Hi. I am Gregory Jackson.
Hello, how may I render you 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, we are here to help you.
Thank you.
Please wait for a while.
Ok.
Sorry we could not find any reservation with your name to change your reservation.
No issues, thank you.
Thank you for approaching us.
