Hello, I am Robert Moore.
Hello. How may I render you?
I made a  reservation earlier to attend  my meeting due to some issues that  meeting place has been changed. So I need a few changes in my reservation. Can you please change my reservation?
We are rapturous to help you. Please Give me a minute, I will check the reservation list.
Sure.
Thanks for being waiting. It's unfortunate that we didn't found any reservation by this name.
Ok, no problem. Thanks for your valuable information.
Thank you for choosing us.
