Hello.
Hello, how may I be at your service today?
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?
May I know your name please to check the status of your reservation?
I am Thomas Clark.
Thank you. Please stay online for a while, I will check your reservation status and let you know.
Sure.
Sorry, there is no reservation matching with your name in our portal to make changes further.
That's ok, thank you for checking.
