Hi.
Hello, how can I help you?
Due to sudden change of my business meeting because of some technical problem, I need to change my reservation so can you help me with that?
Sure, could I have your name please?
I am Brandon Parker.
Ok, please allow me a moment.
Sure.
Sorry, there is no reservation with your name in our portal to make changes further.
Ok, no issues. Thanks for the information.
You are welcome, have a great day.
