Hi.
Hello, how may I assist you?
Can you help me to change my reservation? Please check my details in my records.
Sure, I am here to help you. Could you please provide your name to check your reservation status?
Sure, my name is Joseph Jackson.
Sorry to say this, there is no reservation found in my website on your name.
That is fine, not an issue.
Thank you for choosing us, have a nice day.
