Hello.
Hello, how can I guide to day?
Due to my ill health I cannot travel, could you help me in changing the existing reservation?
Can I have your name to check whether your reservation is existed or not?
My previous reservation has done with the name of Steven Brown.
Sorry, there is no reservation found under your name.
May be my brother has changed on behalf of me before.
That's ok, thank you for approaching us.
Ok, thank you for quick response.
You are welcome.
