Hi, I am Mary Evans.
Hello, how may I benefit you?
Due to sudden changes in the dates of summit which was going to be held in the place where I suppose to visit, I want to do some changes in my existing reservation. Please help me with it.
Sure, let me check the data base and get back to you.
Ok.
It's unfortunate that there is no reservation found by the name you mentioned above.
Fine, thanks for the information.
Thank you for approaching us.
