Hello,.
Hello, how can I assist you?
I would like to change my recent reservation, due to my sudden meeting with my chairman on my boarding day. Can you help me with that?
Sure, may I know your name?
Thank you for your response. Ruth Gonzalez, is my name.

Sorry, there was no reservation found in your name.
Ok, No problem at all.
Thank you.
