Hi.

Hello, how can I help you?
assistant
I am Robert Walker.
user
Yes, Robert.
assistant
Can you please change my existing reservation? because my sister reserved me a ticket with a wrong airport and location.
user
Sure, can you please be on hold while I'm going to check your reservation is existing or not in our database?
assistant
Sure, I will be waiting.
user
Robert, there is no active reservation found under your name in our records to do modifications in that.
assistant
No issue, thank you for your time in checking.
user
It's my pleasure to serve you. Thank you for consulting us.
