Hello,.
Hello, may I know your good name please?
I am George Harris.
May I know what kind of service you are expecting from us?
I made a reservation earlier in the wrong date unknowingly, so I want to change my existing reservation. Can you help me in changing my existing reservation?
Sure, I am at your service. Please wait for a while.
Ok.
Thanks for waiting, but there is no reservation found on your name.
It's ok, not an issue. Thanks for your kind response.
Thank you for opting us, have a great day.
