Hello.
Hello. How may I help you?
Can you please help me to change my recent reservation as my meeting is shifted to Las Vegas?
Sure, I will help you. Can you please tell me your name?
Please check with the name Gary King.
Ok, please wait a moment.
Sure, I will wait for your response.
Sorry Gary, we didn't find any active reservation under your name.
Not an issue, anyway thank you for checking.
Most welcome.
