Hello.
Hello, how can I help you today?
Would it be possible to change my reservation, which I have done with my name?
 Sure, can you please mention your name to check your reservation details in our database?
My name is George Thomas.
Thank you. Please wait for a while, let me check your reservation status. Sorry, I did not find any reservation by your name in our database.
That's ok, thank you for the response.
