Hello.
Hello, how can I assist you for the day?
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 Jack Thompson.
Sorry, there is no reservation matching with your name in our portal to make changes further.
No problem, thank you for the information.
Thank you for reaching us.
