Hello.
Hello, welcome to AS agency. How may I assist you?
Unfortunately my friend with an accident, I need to change my existing reservation to some other day, can you help with this?
I will help you for sure, let me know your name to check your existing reservation details.
Previously I have reserved with the name of Rachel Edwards.
Rachel, there is no reservation found on your name to do modifications in that.
Ok, may be there is a mistake during my booking. Thank you for your information.
Thank you for choosing us.
