Hello.
Hello. What assistance do you require from our agency?
I have to change my reservation due to my planned event got postponed. So please help me with that.
Sure, I am happy to assist you with that. Can I know your full name with which you have reserved the past ticket?
Thank you. Please check the reservation with my name Helen Lewis.
Ok, please allow me a minute to check your ticket status.
Sure, take your time.
I am sorry to tell you that, when I have checked in our portal, I didn't found any active reservation with your name to do modifications.
Oh! It  may not be booked properly. Anyway, thank you for your time.
It's my pleasure. Thank you for approaching us.
