Hello.
Hello, how can I amend you today?
I already have an reservation to attend at my meeting, due to some problems meeting place has been changed. So I need a few changes in my reservation. Sure, you can check my reservation on the name of Raymond Turner.
Sure, we are happy to assist you. Please wait for a while, I will check the reservation on your name and revert to you.
Sure.
Thank you for waiting, we did not find any reservation on your name.
That's Ok, thanks for your information.
Thank you for availing us.
