Hi,.
Hello,.
Myself Kathleen Brown.
How can I provide assistance to you?
I already have an reservation to attend a meeting, due to some issues meeting place has been changed. So I need a few changes in my existing reservation. Can you please support me in changing my existing reservation?
Sure, I am mirthful to help you.
Thank you.
 Please hold a moment, let me check with the reservation list  and let you know the status.
Sure, I will wait for your response.
Thank you for your valuable time.
My pleasure.
 I have checked in the reservation list to change your details, but could not find any reservation with your name.
That's ok, not really a problem. Thanks for your prompt response.
Thank you for approaching us. Hope to serve you again.
